HA! Got me with that one.
A few bad ones..."The Boss" can't sing his way out of a wet paper bag, he just hollers.
Bob Dylan pretty much sucked, Grateful Dead, same thing. Judy Collins never saw a note she liked.
Neil Young was tonally accurate pretty much, kind of whiney, but I liked him (until he got political)
Somebody on the Internet said, “Who died and made him boss”
Someone else said, “He's not the boss of me.”
Which reminds me of the time I was at a Rasputina concert (Cello Rock) and someone shouted out a request, “Play ‘All Tomorrow’s Parties’ (or whatever song) and the lead singer shouted back, “You’re not the boss of me!”
