I hate to be *that guy*, but no Led Zep on Apple could mean that the Jeff Beck Group stays together longer - and The Who for that matter.. which would be pretty good for hard rock.
The runaway success of Led Zeppelin in 1969 put a lot of pressure on those bands - infighting pretty much torpedoed Beck's band, but the drinking and drugs situation in The Who - especially with Keith - was appalling. If they hadn't lost Keith in 1970, I think their next album would've been something.
To be honest, no other label even cared about what Jimmy Page was doing post-Yardbirds. Remember that quote from Ahmet Ertegun (Atlantic Records) after he heard their demo?
"Every band these days wants to be loud. It's the new 'Flower Power'..."
It's very easy to imagine them just gigging a bit, then falling apart & being some obscure cult band.. especially since Jimmy was pretty much managing them himself until Apple stepped in.
[OOC - sorry guys, this was veering a little close to "too good to be true".. I'm a big Who fan, but this DBWI needed some dark. ]
