And yes, it was.

Styx opened with "Blue Collar Man," the first in a long list of the night’s iconic keyboard lead-ins. Performing favorites as far back as "Lorelei," their high energy kept fans on their feet. Tommy Shaw and James “JY” Young continually engaged the crowd and it was thrilling to watch them perform. Keyboardist Lawrence Gowan's showmanship provided highlight moments.

Styx was joined by founding member Chuck Panozzo for much of the show. Notably, Bangor fans had a special treat when Ted Nugent joined Styx with his tiger-striped guitar to perform "Coming of Age," a Damn Yankees hit he shares with Tommy Shaw.

Wrapping up with "Renegade," Styx could have just stayed on stage and played it all again – the fans would have let them.

In ending the night, REO Speedwagon's front man Kevin Cronin was as solid as ever during the band’s 12-song set. With heavy guitars, Neal Doughty's signature keyboards, and Bryan Hitt’s ceaseless assault on the drum kit, REO covered the hits from the album "Hi Infidelity," as well as older tunes before closing the night with the classic, “Ridin’ the Storm Out.”

Classic rock ’n’ roll is alive and doing well.
