George Brindsley McSween (1919 – September 18, 1957), known as Sir Galba, was a Grenada-born calypso singer and recording artist in the 1940s and 1950s. He was born George Brindsley McSween in the village of Birchgrove, St. Andrews, Grenada, in 1919. A troubled man, he had a relatively brief career and life, but Galba is remembered for his outstanding calypsos and contributions to the development of the calypso scene in Trinidad. He stabbed someone in a nightclub in 1952 and five years later, after stabbing his girlfriend, he committed suicide on 18 September 1957.
