Saw Styx and Chicago tonight at Jiffy Lube. The show was bittersweet. On the one hand, both bands sounded great and the audience seemed to enjoy the performances. Both dug a bit deep into their collections. This was the third time I've seen Styx, and the first that they've played Crystal Ball, for example.
On the other hand, these bands are both nearing the end of their run. Only 3 originals remain in Styx from their heyday. Tommy Shaw who is 72 and looks 50, but sounded raspy. James Young who is ~78 and had to use a stool for part of the show. He also didn't sing. And Chuck Panozzo, the original bass player, who only appeared for the final three songs.
Chicago is down to just one original, Lee Loughnane, one of the horn players. One of the original horn players, Walter Parazaider, died a few weeks ago though he had retired in 2017.
Enjoy these bands while you can, though Skynyrd and Foreigner are coming to JLL soon and neither has any originals remaining.
