Although I've always preferred Donovan's "musicality" and singing ability over das Dylan as expressed in the usual ballads and such that is always on the short list of Donovan favorites,
I must say that the song that I remember still raising the most hairs on the scruff o' me neck was ,as still is ,the very electric
"Hurdy Gurdy Man".
Sorry but I'm very much a product of that 2nd wave of "electrified" Brit musician virtuosos ; the ones that made the Beatles sound like so much "bubble gum" Pop until they woke up produced "Revolver". But I'm talking about the rise of Clapton ,Beck,Page, the British-sized Hendrix ( an influence without whoich hendrix would "nver" have made the impact he did )&
Keith Emerson ( always the Hendrix of the keyboard ).
I mention this to tell of a YES tour some 20 odd years ago where Donovan was the 2nd string act and then later joined YES for a truly electric performance of his "Hurdy Gurdy Man".
If only a bootleg recording existed of that "live" performance if just to hear how YES' Steve Howe performed the electric lead.
Musta been a moment to say the least.
