Greatest Country Duets – Who Is Your Favorite?

Listening to WBKR as I always do, this morning I heard the new duet from Brad Paisley & Carrie Underwood "Remind Me" it got me to thinking about all the great duet partners over the years like Conway Twitty & Loretta Lynn,  Kenny Rogers & Dolly Parton,  George Jones & Tammy Wynette, Waylon Jennings & Willie Nelson,  Alan Jackson & Jimmy Buffet and so many more! For me I would have to go with Conway & Loretta as my all-time favorite duet partners,  it was like they we're meant to sing together.  Check out the video with the great duo,  doing what they do best throughout the years!Who is your favorite duet partners past or present?
