Let It Go (Steve)
Another Hit And Run (Split Solo, sounds like Steve, then Pete)
High N' Dry (Pete - watch the video again)
BOTHeartbreak (Steve)
You Got Me Runnin' (90% sure it's Pete)
Lady Strange
http://www.youtube.com/watch?v=rlbqADvY2HYThis video shows Steve playing the solo, but he doesn't follow the album version very closely. So I wonder if Pete has the solo on the album?
On Through The Night (Just guessing here, but it sounds like Pete.)
Mirror Mirror (Steve)
No No No (Pete - according to Def Leppard's 1984 song book)
I've watched as much video as I could find from Pete Willis over the years and he has a few small things that he does differently than Steve. If anybody knows for sure, please correct me but my educated guesses are above.
