Thats true! Although All Time Low has had their tour manager do back up vocals for as long as I can remember. Every time I've seen them hes always been there.
ahhhhh dating myself here, but back when put up or shut up just came out they didn't have to. i miss those days, but they sound good as hell these days so it's whatever.
[inb4: cool story,brah]
also, I remember seeing Alkaline TRIO when they had their 4th guitarist after Crimson came out. I'm still confused about that one, just out of the sheer fact that they were always ALK3. haha.
