I'd repeat Laura's slogan, "Shut up and Sing," but Bruce has NEVER even been capable of that, so I'll stick with the latter half with personal embellishment...
"mr. springsteen? Shut the hell up! ...until you can offer - well - anything to the legacy of mankind."

... Or maybe that should have read 'former,' as in 'just shut up!' Oh well, at least I get to say it again a different way:
Hey bruce... you should be careful about offering your unsolicited opinions. It would spare you the embarrassment of learning what little value they actually have.
