Re-write
Whatever the provenance of the phrase, “Rock and Roll is folk music….”, it’s true. Evidence:
Robert Fripp has twice re-written Fleetwood Mac’s masterful instrumental single “Albatross”. First with Daryl Hall (sic) on vocals as “North Star”, then with Adrian Belew (and King Crimson) as “Matte Kudesai”.
(Apologies for the YouTube links with boring video; it’s the easiest method of offering up the songs.)
