Harry Belafonte's "Calypso" LP on RCA LPM-1248.. by all accounts the first million selling LP... includes a number of tracks written by Lord Burgess which became classics... "Day O" of course!.....this LP was released in 1956.... my copy based on the RCA matrix lettering system seems to be from 1957....nearly 50 years old. its interesting to note that Elvis Presley's first LP came out almost at the same time as LPM 1254..."Calypso" is a fabulous beach record.. nothing like it in the world....
