told Guitar World that he was relieved at not having to deal with the pressure of writing the lyrics anymore). The instantly recognizable opening riff to "Thunderstruck" features Young alternating between fretted notes and playing the open string. In a 1993 interview with Guitar World's Alan Di Perna, the guitarist recalls, "I was just fiddling with my left hand when I came up with that riff; I played it more by accident than anything.

In a February 1991 interview with Guitar World Angus Young stated, "I think the funniest song on this album is 'Mistress For Christmas.' That song's about Donald Trump. He was big news at the time, so we thought we'd have a bit of fun and humor with it." In the same interview, he declared that his best guitar solo
