I have been fascinated with "musical links" for years - used to collect the "Pete Frame Trees" - sad as I am... So, you start with an artist and see how you can link them with other acts, artists, etc ie Deep Purple to Spirit (direct answer, if not known, is Randy California deputised for Ritchie Blackmore Quebec 1972, who was sick mid tour - even got an encore - would love to get a copy of that gig, but never heard of one - they even played "When A Blind Man Cries", so I have read...) or Lynyrd Skynyrd to Lulu (Freebird to "playin' this for Duane and Berry" to Duane Allman's multiple session works - Lulu recorded an lp with the Muscle Shoals crew - actually some excellent RnB work)
This is an obscure link and took me by surprise when I googled the pair in question having never heard the song before...
Being somewhat interested in Neil Young, I have long known that Mr Young played in a band called "The Mynah Byrds", fronted by Rick James, back in the mid sixties, prior to travelling to LA and on into musical history...
So I was rather surprised to find this youtube of a song with a slideshow of pictures - the song features Neil Young, but the thing that surprised me was 2 of the pictures feature Bruce Palmer (also later in the Buffalo Springfield with NY), but to my surprise it shows him playing what looks like an EBO...
This links to an article with the EBO pic, but the top picture shows a Gretch like bass...?

The Mynah Byrds also featured a chap that went on to Steppenwolf...
