Hey Mike, I'm sure this is on your list of faves somewhere, but a couple days ago on XM's Deep Tracks station I heard Tom Petty's weekly show (which if no one else listens to XM, is a mellowed out version of Underground Garage, but with equally obscure tracks & some commentary by Petty after each 4-5 song set).
Anyway, he played The Staples Singers "Who Took The Merry Out Of Christmas?" & I had never heard it before, but totally loved it.
On 96.5 I also heard a Sinatra duet with...wait for it...Cyndy Lauper(!), and I was so stunned when I heard the ID that I forgot which Xmas standard it was that they'd done.
Lastly, I guess this has been around for a while, but I'd never heard it until this year on 101.7, and it's pretty funny. Has anyone heard of the 10-man a capella group Straigh No Chaser? Here's their hilarious take on
The 12 Days of Christmas, a very unconventional medley.
