"It's a Long Way to the Top (If You Wanna Rock 'n' Roll)" is a song by Australian hard rock band AC/DC. It is the first track of the group's album T.N.T., released in December 1975, and was written by Angus Young, Malcolm Young and Bon Scott. Musically, the song is notable for combining bagpipes with hard rock guitars, drums, and bass guitar; in the mid-part of the song there is a call and response between the bagpipes and the lead guitar. It is recorded in B-flat major, but played live in A major.
