i'll offer an entry from uncut magazine january 2008, that i've just found. in a feature titled "worst gigs ever seen"
LED ZEPPELIN MEMORIAL HALL, KANSAS CITY, 1969".
"i saw led zeppelin pretty early on. they did a quick stopover in kasas city and played on a local band's equipment (blues garden). during the set change, a guy came on stage, stripped to the waist, wearing a cape and a zorro hat. he opened his cape and began shouting gibberish into a mic, it was john bonham. apparently, the band killed some time in the afternoon at a nearby Shakey's pizzeria, chugging beer and in bonhams case, whisky. he was blackout drunk.
their first song was 'whole lotta love'. page did the opening riff and bonham just sat there. it became evident that there was a roadie behind him holding him upright. he would sporadically snap out of his coma and pound out some licks completely unrelated to the song, then slump over. at one point, JPJ hit him in the head with his bass. nothing. page killed time with his violin bow guitar schtik. when they'd met their contractual obligation bonham promptly vomited on the drums and passed out"
