I just came into a bootleg Led Zeppelin concert from 1977 in Cleveland. The sound quality is pretty good. A good acoustic set and plenty from Physical Graffiti. There’s an especially hot version of Ten Years Gone.

Disc 1 :
The Song Remains the Same
The Rover
Nobody's Fault But Mine
In My Time of Dying
Since I've Been Loving You
No Quarter
Ten Years Gone

Disc 2 :
Battle of Evermore
Going to California
Black Country Woman
Bron Y Aur Stomp
White Summer/Black Mountain Side
Kashmir
Jimmy Page Guitar Solo
Stairway to Heaven
Rock n' Roll
Trampled Under Foot

I fully realize that most people couldn’t give a shit about this because it’s not some breathy thin-bearded boy band or a group of depressed, post modern indy songwriters, but, in the off chance that someone out there has taste, be aware that this thing is making the rounds.
