April Wine added Brian Greenway to the group in 1977 during the recording of First Glance. After April Wine broke up in 1986, Brian embarked on a solo career and recorded Serious Business which continued the traditional April Wine mix of heavy rock and ballads.

When the band got back together in 1992, Brian abandoned his solo career and rejoined to become a mainstay.
