This is Kara's Flowers' allegedly unreleased song, Angel in Blue Jeans. However, the only copies of the song I could find are slightly corrupted and of low quality.
Feeling sorry for the otherwise really good track, I decided to repair the damaged portions (which aren't a lot, admittedly) and remaster the song a little to give it more "body," so to speak.
Enjoy good people :)
