These are the audio files for The Best of Bond. Download the file for your part, plus the file that is just called The Best of Bond , which has all parts.
An MP3 player should recognise the files as being part of an album called MCC July 2013.
In terms of instruments used, the file with all parts has the soprano/alto line using a violin and the tenor/bass part using a bassoon, with the accompanying piano part. In the individual parts, all the other singing parts are silent, your part is played as a violin (for soprano/ alto) or a bassoon (if tenor/bass) and the piano is quiet(ish).
