According to Randy Bachman's autobiography, the seeds of the BTO sound were sown at a university gig in Thunder Bay, Ontario, shortly after Allan's departure. A promoter, disheartened with reactions to Allan's country-flavoured songs, which the band was still playing, decided to sack Brave Belt for the Saturday night show and bring in a more rock-oriented replacement from Toronto. When that didn't materialize, he begged Brave Belt to stay on and play a set of classic rock cover songs. As the band played songs like "Proud Mary", "Brown Sugar" and "All Right Now", the dance floor filled up and, according to Randy, "We instantly saw the difference between playing sit-down music people could talk over and playing music they would jump out of their seats and dance to."
