Straight No Chaser's Don Nottingham says the list of living musical legends "starts with Paul McCartney," and he'd always consider a collaboration with McCartney "totally unfathomable." 

He adds that it's "totally unbelievable and a true honor" to have him on one of the group's songs. 

"Wonderful Christmastime" is one of the eight tracks on Straight No Chaser's upcoming EP Under the Influence: Holiday Edition.  And Sir Paul isn't the only big name featured on the disc.  Cee Lo Green and Colbie Caillat are also included, along with the late Otis Redding. 

Under the Influence: Holiday Edition will be released October 29th.
