van der Kvelk, Jan: Keyboardist who joined David and Nigel’s London-based band, the Thamesmen, in 1965 at age 16 while band was touring the Benelux nations—Belgium, the Netherlands and Luxembourg—on the strength of their first single, "Gimme Some Money." The teen met the band while they were playing Amsterdam’s notorious Long-Hair Club. Van der Kvelk’s Dutch music connections helped the Thamesmen land gigs, as did changing their name to the Dutchmen. When the band returned to England, van der Kvelk remained in Holland.
