I'm sorry, but Buffy the Vampire Slayer was one of the best shows ever on television and the musical episode, "Once More with Feeling" is a masterpiece of musical storytelling. Since I had the sheet music for the episode I decided to do one of the excellent songs that Joss Whedon wrote, and Spike's song is probably the only one I could sort of do justice to.
All of the episodes of Buffy are on Netflix. The lyrics of the songs in this episode may not mean much to you but the music and production is highly recommended. Check it out.
