Which song was planned to be the 3rd A-side in "BLUE BIRD"?

[Coelacanth]

I think it was JEWEL. I think Ayu decided not to put it on the single in the end because she was planning on releasing a mini-album and didn't want five songs to have already been heard. momentum doesn't fit, I don't think 1LOVE was even near completion. However, I think JEWEL was completely finished in the summer of '06 along with BLUE BIRD/Beautiful Fighters. I think JEWEL could've fared on a summer single, I don't think it was meant to fit any season in particular, there's nothing in the song mentioning snow, cold air, or autumn leaves...

I agree the song is really polished, but I don't think the lyrics are very (A-side) single friendly.
