Ayu songs not at karaoke!!!

[shizukanaotoko]

I love singing Ayu at karaoke but there are a few original songs I just can't find ANYWHERE!

Memorial Address
ever free
+ (though I don't like it anyway lol)
flower garden (same as above)

I'm assuming the lack of availability of the first two is due to personal reasons (both about the passing of relatives) but I wish I could sing them!

Has anyone ever found/sung the above songs at karaoke?
