May 5 (UPI) -- NBC has announced it is planning a 2-hour special called ABBA: Thank You for the Music, An All-Star Tribute, in December.
The Swedish pop stars -- who are known for hits like "Dancing Queen," "Mamma Mia," "The Winner Takes It All" and "Take a Chance On Me" -- announced last month they had reunited after years of estrangement and recorded new music.
