I was lunching with two of Horslips – originators of Celtic rock – yesterday and much badinage was exchanged, with the conversation turning to things ‘that Donovan invented’ (i.e. things he didn’t). ‘Obviously, he invented Celtic rock,’ I said, to chortles all round. And then I vaguely remembered something. ‘Hang on… y’know, I think he *did’ record a track called ‘Celtic Rock’… Jim locked it up on his gadget – sure enough, in 1970, a year before Horslips began, Donovan recorded ‘Celtic Rock’. Gobsmackery all round. Situations in which one realises that, yes, the Don *really did* invent something must be rare indeed! 😀
