Many years ago while listening to Stephen Stills 1 with my father, he mentioned that the track Go Back Home was the only studio recording that featured both Jimi Hendrix and Eric Clapton playing guitar together. There were of course famous live performances featuring them both, but for sound recorded in a studio this was supposed to be the only occurrence.
I know that the album was released shortly after Jimi's death, and dedicated to him, but it is hard to even get confirmation that these are the two guitarists who are playing on the track.
The Wikipedia page for the album almost confirms this, but the exact phrase used is "the only album to which both Eric Clapton and Jimi Hendrix supplied guitar work" (italics mine) which doesn't quite match up, and the list of contributors by song only mentions Eric Clapton as the guitarist on Go Back Home, whereas Jimi supplied guitar for Old Times Good Times.
Is anyone able to supply a counter example to disprove this, or perhaps prove it via a quote from one of the two? Or should I be asking elsewhere?
