Too many to list them all. A few of mine, in no particular order:
Brian Robertson (Thin Lizzy) Cowboy Song
Pete Willis (Def Leppard) Rocks Off
Alex Lifeson, La Villa Stangiato
Eddie Van Halen, Hot For Teacher, Feel Your Love Tonight
Stevie Ray Vaughan, Lenny, Love Struck Baby
Gary Moore, Remembering (With Love)
Myles Goodwyn (April Wine) Crash and Burn
The solo in Boston's Hitch A Ride, I am not sure who played it
Ted Nugent (Dam Yankees) Come Again, Stranglehold
Eric Johnson, East Wes
Glenn Tipton (Judas Priest) Living After Midnight
I can't really pick a favorite.
