Live covers/atypical songs?

[StarSUCKER]

For those concert junkies: what songs has Ayu sung live that are not part of her discography? I don't mean "official" covers like Sotsugyo Shashin or teens, but songs that are otherwise not associated with her. I know of the following three:

Chako no kaigan monogatari (チャコの海岸物語)
Haru yo, koi
Tokyo

Is this it, or are there any unconventional song performances I can add to this little set? Thank you~

Edit: I mean post-idol songs. Stuff after she joined Avex.
