"Once More, With Feeling," the musical "Buffy the Vampire Slayer" outing that was the best single episode of any TV show on any network this season, gets a repeat showing this week (8 p.m. Tuesday, Ch. 44). The words and music by show creator Joss Whedon are a brilliant piece of business, and even though the cast members are not equally talented in the song-and-dance department, everyone manages to get through the numbers with aplomb. Be sure to check out the duet between Willow (Alyson Hannigan) and Tara (the big-voiced Amber Benson). It's one of the sexiest things you've ever seen on American network TV.

** NOTE: Under Your Spell is Amber's solo. It was not a duet. The article is incorrect.
