After attending York University, Humphrey dropped out of the theatre program to pursue music full time.

[2] Humphrey sang lead, and was known for his low-timbred singing, compared at times to that of David Bowie[3] and Bryan Ferry,[4] as well as his "suave" looks[5] and dancing style.

His band mate Geoff McOuat credited the singer as being influenced by Frank Sinatra, Elvis Presley and elements of film noir.

[6] Humphrey and Blue Peter performed shows occasionally, often as part of "retro" events, such as the Juno Awards 40th Anniversary Concert Series held at the Horseshoe Tavern[7] in January 2011.

Humphrey died at the age of 61 on April 4, 2021, after a long battle with multiple system atrophy, a rare degenerative disorder.
