Has any British music exec, producer, recording engineer, etc. - or Jimmy himself - ever documented all of the songs he played during his session career? I have read what all of the Zep bio's talk about, but if he truly played on as many recordings as legend says, there are hundreds of tunes I am unaware of. If anyone knows of the list, I'd like to see it so I can add the songs to my music collection. If no list exists, maybe the fans here can built it. Thanks.
