“An epic song, that one. We put so much into it. Rick Savage had this idea on guitar, and I literally sang the first verse over the top of it. I said, ‘Oh, I’ve got this bit – I gotta know tonight…’ We took it to Steve, Joe and Mutt, and they added their parts.

“Rick Allen had suggested that we called the album Hysteria, so we decided to call the song the same thing. Once we had the basis for it, it was just a matter of getting all the parts down.

“On the ‘gotta know tonight’ part, we recorded every guitar string separately so that there would be no arpeggiating. Mutt said, ‘I don’t want a keyboard doing it, I want it on guitar.’ It had to sound non-arpeggiated. Because even if you hit a power chord, there’s a certain amount of arpeggiation. But if you hit every note separately, it sounds totally different. It’s a brilliant sound.

“Steve and I played the solo live together in the studio. We did the same notes, but our vibrato techniques were quite different. We both went through Rockmans. I was playing a Strat, and Steve played a Les Paul.”
