I have most of their solo career albums... I just don't have a few of'em yet, hmm...let me see...
Paul's: "Choba B CCCP" and his classical works(I just listened to a friend's CDs).
John's: "Two Virgins"(I NEVER've been curious[:D]),"Live Peace In Toronto" and "Unfinished Music 1 and 2"(same on "TV", I can't stand Yoko-san's whispers, gaspings and squeals...LOL[:D]).
George's:"The Best Of Dark Horse"(just have the unedited songs on cassete like "Poor Little Girl","Cheer Down" and one that I can't remmember the title)and "Live In Japan"... I have Wilburys 1 but not the 2, though I don't consider those as George's albums but as his collaboration to a temporary formed stars group(AWESOME group, have to say).
Ringo's:"Beaucoups Of Blues" C&W that I'll get someday yet, "Bad Boy"(on a lost cassete, but I don't miss that), "Storytellers" and his All Starr Band tours(I don't have on CD but on DVD).
