'Flick of the Switch' and 'Nervous Shakedown' were both issued as singles. 'Brainshake' which is also on there but Sydo forgot to list, was on a compilation called 'Metal Madness' too.
This thread is cool. It reminded me how much I loved the album, so much so I went out and bought the remastered digi-pak version last night from Kmart!
