I Don't Intend To Spend Christmas Without You
There's nothing I like more than oddball covers of songs. Even though this is not a cover of any one song, it borrows heavily from several other songs--most notably The Association's "Windy" and a song by The Monkees whose title escapes me. It might as well be a cover!
What makes it an oddball is its sixties arrangement (complete with the classic tic-tac bass sound) coupled with Longet's accent. She sounds Japanese most of the time, which is damned odd.
Unfortunately the song is not commercially available now. Luckily it's on YouTube, or if you're like me and enjoy wading through mp3 sites of holiday music, it can still be had.
