1) Record one of the wonderful songs your ex wrote and made famous, and do a whole verse in his trademark growling wheeze, highlighting just how silly it sounds.
2) Place this song on the same album as a heartbreaking ode to the relationship you once had, with all the wistfulness and bitterness mixed up in a haunting melody.
3) Watch your record climb to #11 on the charts.
Dig it, Joan Baez.
