In 1970, Wilcox replaced Amos Garrett in Ian and Sylvia Tyson’s band, Great Speckled Bird,[2] playing backup for acts such as Anne Murray, Carl Perkins, and Charlie Rich.

David first played with the Rhythm Rockets, a band that featured Dennis Stillwell Martin on vocals, harmonica and guitar.

After several successful years with the Rhythm Rockets, David Wilcox hit local stages in the Teddy Bears as a flashy character with an oversized waxed moustache, a baggy suit and a flower in his lapel.

In the late 1980s, Wilcox moved away from his past raw live-in-the-studio approach, to a more produced synthesizer and drum program modern rock sound.

The album Breakfast at the Circus (1987) featured "Layin' Pipe", "The Song He Never Wrote", sounding like a Wilcox tribute to his excessive side.

The album, recorded at Metalworks Studios in Mississauga, Ontario, features sax-and-organ jazz ("Rainy Night Saloon"), country storytelling ("Shotgun City") and deep blues ("Three Past Midnight").
