I think KISS has been doing a farewell tour for twenty years
They need money!
Led zeppelin. everybody else ran out of money or the"time ole signs" calls them back to duty or both. song lyrics' are deep. In 2012 I was fortunate enough to get a rare edition of a published rock n roll manifesto. that got stolen from me, but at least I still have my rock n roll hall of fame museum t-shirt here. Go to the museum in Cleveland and you'll benefit a great deal. They have farewell tours yet many are resurrected in a sense.
Farewell doesn't mean forever. I can say farewell and see someone again in an hour
Scorpions? Maybe not really a "rock n roll" band but..they've said "goodbye" quite a few times.
They are/were a band!Not a "rnr" band though.
