Haha, well yeah, I was hesitant to say we had footage of almost everything but then I pulled back when I considered that official DVDs and Live CDs are pretty much what the average fan would go by. Which I estimated 75% of their discography is represented again live, on these releases, so I should have added this consideration.
So yeah, I just actually bothered to count, and it seems there are 102 studio DT songs that are on the official albums and that doesn't even count any B sides or bonus tracks and I merged stuff like 6DOIT or ITPOE parts as one count. Then I counted the songs that are represented on official release only (not even counting official bootlegs just: Marquee/Livetime<+5years>/Budokan/Score/Chaos/Luna). And it would seem that 79 out of the 102 songs have official live versions which is quite an impressive count if you ask me. Even though there's actually almost 90 songs from these live releases as some obscurities that were played, weren't included on a main album. (Bombay Vindaloo/Another Won/FII B sides etc.) If I had pulled the stat '77.45%' of album songs had been represented in official live albums' it would have been more accurate apparently.
Could probably collect different stats if we included more content but I just tried to keep it simple; if you could call it that, so I'm not doing it again.
In any case, I think it's amazing that they've played almost everything they've ever written live (as DT), save for an ancient B side and a very obscure instrumental. And then represented most of what they've played on live releases, it's pretty awesome really. Bands like Rush have represented a huge amount of their songs as well, but as I understand it there are still quite a handful of songs that they haven't even touched at all after they made the album and most bands only play the hitz.
EDIT: Oh I forgot to refer TBOT
. I was counting Don't Look Past me and Raw Dog as the 2 unplayed pieces.
