While one might question if it really has lyrics, in "Double Barrel" (1971) Dave and Ansill Collins shout "Soul power!", which was the title of a James Brown hit several months earlier. And in 1994 the "Double Barrel" title was heard in Beck's "Loser".
Not quite exactly the same lyrics, but an interesting coincidence in the 8/11/73 AT40. Johnnie Taylor was at #12 with "I Believe In You (You Believe In Me)", and up next at #11 was Chicago's "Feelin' Stronger Every Day", which opens with the line "I do believe in you, and I know you believe in me".
