'Dancing With The Stars' had a sock-hop feel for a moment last night as the Macey's Stars of Dance paid tribute to the late Dick Clark.

Some of the originals 'American Bandstand' dancers were on hand as a bevy of dancers sported '50s outfits, and honored America's oldest teenager three weeks after his death. 'Dancing' host Tom Bergeron called Clark "An American Treasure."

But it wasn't all good news for DWTS fans last night, as the show did a little house cleaning in anticipation of next week's semifinals. Roshon Fegan and Chelsie Hightower, and Melissa Gilbert and Maksim Chmerkovskiy said goodbye, in the dreaded double elimination. Bad news for Gilbert, on her 48th birthday!
