Megalomanic was a b-side to Preacher Man. It was even a shorter mix as the b-side is 4:26, while the album version is 6:16. I thought it was a strange choice for Outta Sight to be the b-side of Long Train Running. So 2 b-sides ended up as album tracks. It's a shame that Only Your Love and Tripping On Your Love had no proper b-sides either, only a remixes.
The Pop Life era was fabulous, but the lack of proper b-sides (not album tracks) was something lacking for the fans. The SAW tracks from 1988/89/90 could have been b-sides. Even the track Some Boys (from the 2013 Deluxe Edition) could have made a nice b-side.
The album was intended to have the Youth mix of Ain't No Cure, but SAW reminded London records of a deal they had made with 2 tracks getting on the album. Thus, the SAW mix of Ain't No Cure replaced the Youth mix and Heartless was added to the CD. The South Korean vinyl release has Heartless on it, too. The more you know!
