One of the most upbeat songs of all time (and one of Matt Herkimer's favorites) is "The Happiest Girl In The Whole U.S.A." by Donna Fargo. Forty years ago today, that was the number one country song in the country, and we're featuring it on our "Country Classic Double" at 11:30 a.m.

Here's a vintage video of Donna Fargo (with all those curls) singing "I'm The Happiest Girl In The Whole U.S.A.".

Enter Donna Fargo as the first artist of today's "Country Classic Double' in our Rewards Club for a chance to win cash and prizes.
