Find three to five other people in your network (virtual or otherwise), and cajole/ask them to agree to sing and record the same song. Then, have one of you collect all the audio files and superimpose the songs into one chorus (e,g. via audacity or garageband) of collective voices. Some tools that might be handy are Vocaroo (recording voices, no sign-in, downloadable files), or Soundation (a free online audio mixing site). Another one some have used to good success is Soundtrap. You can share out via Soundcloud or some other hosting site. Be sure to share out your collective voices for us to hear. You sound beautiful, by the way.
