I see you were at above concert. I have a source showing the band "Barooga Bandit" (from Birmingham, MI) was opener that night rather than the British band you have listed. Any chance the ticket just abbreviated the band name oddly? See: https://www.vharchives.com/vhtour1978

(They shortened the name to just "Barooga" after first album.)
They also fit the time frame well with debut singles/LP in 1979.
