1975 found the band engaged in highly successful tours of Europe and the US, wherein BTO was supported by Thin Lizzy, an emerging band also on the Mercury Records label. Said Randy, "Lizzy were just opening in England, but our label wanted to bust them in the rest of Europe and break them wide open in the States, so we toured with Phil and the boys for seven or eight months." With management pressure to capitalize on their growing success, BTO quickly recorded "Four Wheel Drive" in May 1975, which included the single "Hey You". Although reaching no higher than No. 21 on the US charts, "Hey You" would become BTO's second No. 1 single on the Canadian "RPM" charts. Meanwhile, the album charted in the Top Five in both the US and Canada.
