With all due respect GeminiMALE40, I would hardly call a band that is STILL together and touring non-stop for more than 4 decades a "HAS BEEN" group.
Granted, their new album is the first to be released in quite some time, but a lot of bands have taken a break from recording for several years at a time.
As for no one ever singing one of their songs at your shows, that may be a matter of geographical and age related demographics. I personally sing Fantasy, Boogie Wonderland and Got To Get You Into My Life. Just last week at my Friday show a 20 something year old guy sang September, and brought the house down. It was awesome!
