Longtime AC/DC lover here. Had tickets to go to a gig on the '91 tour but illness meant I didn't make it So they remain one of the few of my favourites that I have yet to see in concert. If push comes to shove, I would have to go with Bon..simply because I like more of the albums that involved him. Kudos to Brian though, he is a great frontman and to fill the boots of someone like Bon takes some (big!) balls. As for songs and albums...Sin City is awesome, as is TNT, Dirty Deeds.. Hells Bells, Who Made Who, You Shook Me All Night Long from Brian. Back In Black is one hell of an album. Also rate Dirty Deeds Done Dirt Cheap, High Voltage and Powerage.
