Don’t forget, Issac sold Gravity Rides Everything to VW a few years back for a VERY popular comerical series. But yeah, it’s really hard to say how big a band has to get. My Dad grew up with a couple of guys from the band The Knack. Remember them? Sorta? A one hit wonder band, who’s one hit happened to be My Sharona. Berton doesn’t work anymore, not unless he wants to. Not really. But they never got really big either.
