Two ghost stories
Since I have mentioned that monster that is relationships, humour me and allow me to post something pointless, and maybe even daggy: two old songs about the ghosts of old loves. One is male, one is female. One is all high drama and legendary epics, the other all feigning nonchalance and denial (I’ll leave you to work out which is which). For different reasons I like them both.
Ghost, by the Indigo Girls (these girls do good vocal harmonies, and allude to the legend of Troy)
Ghost Story, by Sting (listen for Vinnie Calauita's unusual drumming around the middle)
