Walter "Zwol" Zwolinski (aka Zwol or Walter Zwol) is a Canadian musician and songwriter and founding member and front-man for the Canadian rock band Brutus (1969–1976). The band charted a minor Canadian hit, "Who Wants To Buy A Song", a #65 hit in 1976. Zwol then embarked on a solo career and charted two Top 100 hits in the US and Canada late 1970s. He continues to record and perform live in the Toronto region.

Formed in 1969, Brutus consisted of Zwol as vocalist, Tom Wilson as bassist, Michael Magann on trumpet, Lance Wright on drums, Eldon "Sonny" Wingay on guitar, and Bill Robb on sax and trombone. The band was the opening act for popular Canadian and American acts that were touring Canada.

The group disbanded in 1971, then reformed with a revised line-up and new look in 1973. The new Brutus lineup recorded two singles on GRT Records in 1975, with "Who Wants To Buy A Song" and "Ooh Mama Mama"becoming their most successful recordings. Their debut album would follow in 1976 but only two additional singles would follow before they disbanded. ^[1]
