Then remember there was Jimi Hendrix playing Star-Spangled Banner.

Waterson-Carthy singing madrigals - now I'd like to hear that. The same goes for Kate Rusby singing Marie Lloyd. But I'd draw the line at the Pogues "Best of Noel Coward." (The other way round might be quite enjoyable, if only Noel Coward's services could be obtained. "Fairy Tale of New York", perhaps with Joyce Grenfall for the Kirsty MacColl lines.)
