It is the first track of the group's second album "T.N.T.", released only in Australia on 8 December 1975, and was written by Angus Young, Malcolm Young and Bon Scott. The song combines bagpipes with hard rock instrumentation; in the middle section of the song there is a call and response between the bagpipes and guitar.
