Doo-Wop Multitrack: "Earth Angel" (for Chelsea)

My girlfriend is sick, so I arranged and recorded her a song. I hope this helps you feel better Chelsea.

For Chelsea:

This is my first doo-wop arrangement, and the first full song that I have multitracked. Unfortunately with five tracks at once, the noise on the recording becomes rather annoying. If anyone could help me reduce the noise, I would greatly appreciate it. I plan to write up the arrangement in the next few days (as an exercise) so you can expect to find that soon.

Update:

I typeset the arrangement using Lilypond, a wonderful open source program for engraving music. Here are the results:
