The single, "Roxy Roller", became a No. 1 hit in Canada, holding the top position in the RPM national singles chart for three weeks beginning on June 26, 1976, & winning a Juno Award for the band. Gilder and McCulloch subsequently left the band to pursue solo careers. Gilder had hits including "Hot Child in the City".
Clark Perry was brought in to replace Gilder on vocals, and Skip Prest replaced McCulloch on guitar. Perry did not work out, however, but did record a single version of Roxy Roller and Rue de Chance, Sweeney Todd - Roxy Roller / Rue De Chance, and was replaced within a few months by then 15 year-old Bryan Adams.
The new lineup recorded Sweeney Todd's second album, If Wishes Were Horses. However, that album was unsuccessful, and Adams left the band after less than a year. The band attempted to carry on with Chris Booth on vocals (and Grant Gislason replacing Prest in 1978), but broke up before recording any further albums.
The band re-united in 2000 and began working on The Sweeney Todd LP.
