Seems even contemporary today lol, though it was 53 years ago.
The guitar work is by Jimmy Page.
"Fast" Eddie Hoh was the session muso on drums (Eddie was at the 1967 Monterey Pop Festival as a temporary member of the Mamas & Papas band).
(Remember Session Musos, they were legends before Sony and others decided to digitise all the sounds in the spectrum and provide some “artificial” computer backing to the girl-boy pop groups – it saved Sony money was the story ffs)
