Procol Harum returned to success on the record charts in the following years with a symphonic rock sound, often backed by symphony orchestras. At this it was one of the first groups to achieve success; "" was a No. 5 gold album in the US in 1972, as well as reaching No. 48 in Britain. "Conquistador" (a track from their first album, re-charted for accompaniment by the Edmonton Symphony in 1971) was a hit single in 1972, getting to No. 16 on 29 July 1972 in the US, five years to the date after "Whiter Shade of Pale" peaked at No. 5, and No. 7 in Canada, whilst reaching No. 22 in the UK. Their follow-up album, "Grand Hotel", did fairly well, reaching No. 21 on the US "Billboard" 200 in 1973.
