I am trying to work on improvising on the harp...and I keep listening to a Radio Show Metallica did a while back with some of their good buddies (including John Popper) and it was all acoustic...and I was wondering if anyone knew the keys of the following songs that were played at this show...

1. Low Mans Lyric (i'm pretty sure thats in C, cuz I think I have it tabbed out, its on Re Load)
2. Helpless (a Diamond Head Cover, its on Garage Inc.)
3. Four Horsemen (on Kill 'Em All)
4. Oh Poor Twisted Me (on Load)
5. Creeping Death (on Ride the Lightning)
6. Tuesdays Gone (Lynyrd Skynyrd Cover, its on Garage Inc.)
7. Nothing Else Matters (on Black Album)

Any help would be greatly appreciated...Rock On
