Every Saturday night deserves a spin around the dance floor to the sounds of a rockin’ bar band, and George Thorogood and the Destroyers still fit the bill.

At 74, Thorogood could hang it up after a fantastic career that includes 1980s blues rock hits such as “Bad to the Bone.” Instead, he and his band of five decades are still out there touring with fervor, and he’s still donning black leather pants and making lascivious jokes. But his lengthy career have given his vocals and guitar playing a level of gravel and experience that add to the rock aura.

The lights went down at the Rivers Casino Event Center just after 7 p.m. on Saturday night, and a complete recording of Barry McGuire’s “Eve of Destruction” played before strobing white lights heralded the band’s arrival onstage as a booming voice announced “the undisputed, undefeated heavyweight rock ‘n roll champions.”

Thorogood was full of energy from the moment he bounded onto the stage, bellowing into the mic, “Come on, everybody, there’s a rock party tonight!”

“Rock Party” was the first song they played, and it definitely got the shindig started. Under crimson and white strobe lights, guitars kicked fiery solos into the air and the saxophone blared. Thorogood’s vocals took a little while to warm up, but not for lack of enthusiasm.

“Who Do You Love?” was up next. The Bo Diddley cover was featured on the band’s second album in 1978, and their distinctive blues guitar riff at the beginning is highly recognizable — but this live version was a little fuzzier, a little more psychedelic, a little more reminiscent of the Quicksilver Messenger Service cover from the 1960s.

“Mama Talk To Your Daughter” another cover, was more rockabilly and up-tempo, bringing to mind the darker side of a super-fun sock hop. Thorogood is great at walking the fine line of irreverence that makes a little ditty, well, a little dirty.

After a literally flashy intro — with lots of flashing lights — the band sprang into “I Drink Alone,” one of Thorogood’s own compositions with a gravelly guitar that matched Thorogood’s vocals. He stalked the stage with a casual swagger, carrying his guitar like he would feel lost without it.

Plenty of people were probably there to see “House Rent Blues/One Bourbon, One Scotch, One Beer,” and they weren’t disappointed. The song starts off with a lengthy story that Thorogood still sing-tells with panache, and launching into the roadhouse staple’s big rock chorus, the band was joined by the voices of most of the audience. The riffing and solos here — and in several songs — were a little too long, but clearly well-practiced; the band knows each other’s talents very well.

At the song’s close, someone sitting close to the stage clearly had a request that he made loudly over and over again, and Thorogood obliged him. “If we play it great, which we will, it’s on us, but if we play it badly, it’s on you.”

“Do we have any country and western fans tonight? Well, that’s great, because we don’t play any country and western. We play city music,” he added. Before kicking into a cover of “Cocaine Blues” — most popularly released by Johnny Cash — he dedicated it to “a great artist and a wonderful man, and to the woman who loved him, June Carter Cash.”

Now, “Cocaine Blues” is an amazing song, especially live, and I’m sad to say that I’m not sure they nailed it — the band and Thorogood never synced the tempo up quite right, and there was something off about the performance.

After a fun little instrumental break while Thorogood was absent from the stage where the guitar and saxophone had a very amiable conversation to “Tequila,” they played “Gear Jammer,” a less-bluesy song perfect for driving with the windows down. Thorogood delivered the guitar solo of the night, his ax wailing and whining through the repeated riff of the song.

“When you’re starting out, everyone has a hero, an idol. … We got our hero but I can never say it right, his name is either Mick Richards or Keith Jagger. Whoever that cat is, I owe him a lot. I think we all do,” he said before blaring into “Get a Haircut.” The Destroyers followed that with probably their most famous song ever, “Bad to the Bone.”

For a show that was full of meandering solos and diversions, they stuck surprisingly close to the recorded version of “Bad to the Bone” and still sounded good as ever playing it.

After a spirited rendition of Them’s “Gloria,” they ended the regular set with a big thank-you to Pennsylvania fans and their cover of Hank Williams’ “Move It On Over,” another country classic that hit just the right upbeat tempo before all the lights went down.

Their only encore song was “Born to be Bad,” an airy tune with typically gritty lyrics that didn’t quite match its lighter groove. For this one, Thorogood ditched the guitar and paced around the stage, leaning over to sing directly to the front rows and enjoying himself. The band didn’t have any problem picking up the slack. He stuck around to do some bows and talk to some fans at the song’s end, as a recorded version of “The Star-Spangled Banner” signified the night’s official end.

It should be noted that, despite how bad and dangerous Thorogood says he is over and over again in his music, he was also unflinchingly polite; he told the audience not to drink and drive, and to make sure to tip waitstaff and bartenders. “The people got to take care of the people, or the people aren’t gonna make it,” he said.
