The show was really good, older crowd for the most part (like 40-50-ish and up) They did songs specifically from their second album (Chicago II)
for the first half then songs from their later albums going into the 80's (before Peter Cetera left) There are just three of the original seven performing now, and the others being added over the last few years. Still, it was a great show.
As far as Greyhound, they have remodeled their fleet, and it's a little more comfortable, of course it's more comfortable when it's not packed and you have the seat next to you empty no pics right now tho.
