Orange using Vashti Bunyan's Diamond Day not only relaunched her career but revived an entire lost idiom of obscure UK psych-folk for a new generation. What goes around comes around, if only by dint of a more genuine Folk Process than that gibbered over by folk enthusiasts. In other words, it's the same thing, just a different medium, and I know several people who's lives were changed and enriched as a consequence. For example I might mention Charles Webb, who had local girls Camelia turn in a near definitive rendering of Diamond Day at his funeral. Charles being a life-long Folky, I assumed that it had be a cherished favourite since the the dark daze of Witchseason, but he brother told me he'd fallen in love with the song via the Orange add. Does that cheapen it? I think not!
