Your Chance to Duet With Elvis Presley

Want to sing with the King? Fancy yourself the next Martina McBride?

Hot on the heels of the holiday collection,'Elvis Presley Christmas Duets,' Sony BMG Music Entertainment has created a website where you can record 'Blue Christmas' as a duet with Presley, singing McBride's part from the album.

It's as easy as dialing a phone number -- found at www.singwiththeking.com, accessing a code, and singing your part over the phone. If you're happy with the recording, send it in a Christmas-themed electronic card. (And hope it doesn't get postmarked 'Return to Sender').

Not confident enough in your singing abilities -- just send the Presley-McBride version of the song from the album instead.

Best of all, the entire thing is free.

Launched December 5, the site has thus far drawn 30,000 people from nine countries. While the Presley-McBride promotion ends in January, the site has been so successful that Sony plans a similar one -- which could potentially shatter glass all over the world. It'll coincide with the release of the multi-octave-ranging Mariah Carey's 'The Ballads' collection for Valentine's Day.
