Infinte Dreams - lot of fans were disappointed that Maiden didn't play it during Maiden England, but for me I don't care if they play it or not, so I guess that qualifies in this post's theme.
Also, Stranger in a Strange Land, again, was nice to hear it during FPT but I wasn't crazy about it, if they wouldn't have played it, I would have been okay.
Lastly, Killers, some (or many) are waiting for this song to be played on RFYL tour, but for me, hopefully not, I would rather have some other songs (Afraid to Shoot Strangers, No Prayer for the Dying, or even Running Free if I had to choose).
