Betancourt was chosen with 11 steelpan players to form the Trinidad All-Steel Percussion Orchestra (TASPO) and play in London at the
1951 Festival of Britain, in the same year he toured England and Europe with the band and was the only member of TASPO to remain in England when the others returned to Trinidad on 12 November 1951. Betancourt's calypso "Taspo's Story" features on the
RASPO Rhythms CD by the Reading All Steel Percussion Orchestra (RASPO), relates the tribulations encountered by the arrival of the first Steel Band in London: The Trinidad All Steel Percussion Orchestra (TASPO). Betancourt,
Russell Henderson and Mervyn Constantine, who later on was replaced by Max Cherrie, followed by his brother Ralph Cherrie, formed the first steelband in the UK and performed all over London as well as in radio shows, jazz clubs and the
BBC. In 1955 Betancourt was taught by Tony Kinsey to play the traps drums to form The Henderson combo.
Notting Hill Carnival Henderson, Betancourt and Ralph Cherrie, initiated the multicultural Notting Hill children street festival organised by
Rhaune Laslett in 1964. A festival that grew to become the biggest street event in Europe, the
Notting Hill Carnival.

Zurich, Switzerland, inspired some locals to form their own Swiss group, which they called Tropefieber ("Tropical Fever"), the first steel band in Zurich, followed then by many others.
