They probably would've stayed on the trajectory of trying out new things. I bet they would've made some very dated synth-based music in the 80s along the way but I think they'd also incorporate some more brooding post punk ideas.

Ideally though I'd like to have seen JPJ and Bonham start a new group taking a totally new direction or just falling back on the ultra dank blues rock though.

Either John or Jimmy would have died during the early 80s. John was a massive alcoholic and Jimmy's smack problem had gotten so bad his teeth were starting to loosen.

Hate to say it, but Bonham dying helped to avoid the destruction of the Zeppelin mystique. It was bad enough seeing Page and Plant trying to navigate MTV post Zeppelin.

Bro they'd have totally made 5150 before Van Halen did.

Seriously, Bonham and Page were both toast. Why do you think ITTOD sounds so different? It was a Plant/Jones solo album with JP and JB as guest artists.

Four of the seven tracks don't even list Page in the writing credits. That's Twilight Zone **** for a Zeppelin album.

Someone was going to die during the 1980 world tour if it had ever happened.

Early 1980 during the small European warm-up tour.
He's over 6 feet and I'd guess, what - 120 pounds?

There's a few pics of him shortly after Bonzo croaked and he looks like Walking Dead.
