BZN (short for Band zonder Naam or "Band Without a Name") was a Dutch band. BZN started out as a pop-rock band in their native Volendam in 1966, playing early-Bee Gees-like harmony pop. The initial line-up consisted of Jan Veerman (vocals), Cees Tol (guitar), Evert Woestenburg (guitar) Jan Tuyp (bass guitar) and Gerrit Woestenburg (drums). In the early Seventies, the band switched to hard rock and had its first successes, including a brace of Top 40 hits. After original singer Veerman left and drummer Keizer took his place behind the microphone, the band made a musical U-turn and opted for commercial radio pop, adding female co-vocalist Annie Schilder and laying the foundation for their status as the most popular Dutch band ever (in terms of hit singles and albums). BZN has had over 50 hits in the Dutch hit parade to date. BZN's claim to fame started with the song "Mon Amour" (1976), which held the #1 hit parade ran
