CONNIE Chung shocked and delighted her former co-anchor Dan Rather last night – serenading the CBS newsman to the tune of “Love and Marriage.”

Chung, who co-anchored the “CBS Evening News” with Rather from 1993-95 – an often stormy alliance – materialized as Rather was inducted by Maury Povich into the Silver Circle of the New York Chapter of the National Association of Television Arts & Sciences.

The ceremonies, hosted by Povich (Chung’s husband), came to a sudden halt as Chung walked in and sang to the tune of “Love and Marriage.”

Here’s how it went:

“Chung and Rather/Chung and Rather/How the gossips used to love to blather/None of it was true, Dan/I treasured sitting next to you, Dan.

“Dan and Connie/Dan and Connie/Nothing like Mark Green and Giuliani/As I said to Maury/It’s time to tell the honest story.

“I loved being your co-anchor/Right from the starting/You’d be in Afghanistan/I’d be with Tonya Harding.

“Dan and Connie/Chung and Rather/Time to put aside the past and gather/Glad that I came back, Dan/What’s done is done/You’re number one/And here’s your Silver Circle platter.”

“This is my tribute to Dan,” Chung told The Post. “Maury came up with the idea – and I always do everything my husband asks me to do.”

Last night’s ceremonies also featured inductees Linda Ellerbee, Ch. 11 newsman Marvin Scott and “Today” show weatherman Al Roker.
