I think we can agree that Page and John Paul Jones with Bonham's son and some replacement singer is not the same as "Led Zeppelin." I'm kind of surprised because Led Zeppelin must surely go down as one of the best managed, if not THE best managed, bands of the 1970s. They didn't get screwed by the record company. They didn't stupidly sign away their publishing. They didn't put out crappy filler albums or novelty singles that diluted their brand. When Bonham died, the shut it down and managed their legacy with care. (Unlike, say, The Who, a band whose stature was badly, badly tarnished by poor management and endless efforts to cash in on the back catalogue.)
So what the hell is Jimmy smoking?
