Duane died before it was released but it had already been mostly recorded in the studio. He played on Mountain Jam, One Way Out, Trouble No More, Stand Back, Blue Sky and Little Martha. Pretty sure that was the last album Oakley recorded on as well. Weird how they both died. eff you fate for taking them way too soon!
Another fun fact. Duane played slide and lead guitar (tracks 4 through 14) on Derek and the Dominos - Layla and Other Assorted Love Songs album.
Good factoid there at the end. Many don't know that. In fact, Duane has the main lead in Layla. Clapton said it was simple and easy to distinguish between the 2 in the song. If it's straight ripping, then its Clapton. If its slide and sounds twangy, its Duane. He also does his signature bird whistle towards the end before they go into the slow piano piece and right at the end of the slow piece as well during the fade out.
I like AB as well. Probably not to your degree, but I am probably more like that about Clapton as far as an obsession. So much I named my 2nd child after that song. Yes, Clapton is god.
