I still love all of the old Thin Lizzy stuff and remember the Lizzy/ACDC concert well. My eardrums suffered after that show at the Royal Oak Music theater.
My personal fav off that album is "Don't believe a Word" and here is a great live verson:
Man, this is like "deep cuts" or whatever they used to call it on radio. This is like 70's hard rock at it's best! Too bad the only song I ever seem to here by Thin Lizzy is "Boys are back in town." Shame.
