Bruce Springsteen's new album Wrecking Ball is vying with Military Wives' 'In My Dreams' for the number one slot on the U.K.'s Official Albums Chart with only four more days before sales are tallied.

Springsteen currently holds a narrow lead, but the Military Wives are expected to get a boost in sales from with Mother's Day coming up in the UK on March 10.

The Military Wives Christmas campaign made for one of the most exciting festive chart races of all time--and this week's Official Albums Chart race looks set to be almost as gripping, said the Official Charts Company managing director Martin Talbot in a press release Wednesday.

The Military Wives have a Cinderella story--an all-female choir group, all actual wives and girlfriends of British military service members, who gained attention during fourth season of BBC's reality show The Choir, and were launched to stardom after their debut single, Wherever You Are was released in December last year.

Springsteen, the 62-year-old native New Jersey son, will not yield the Official Albums Chart throne to the British choir group so easily. The Boss has sold over 6.5 million albums in the UK and an estimated 64 million in the U.S., according to Official Charts. His highest selling album was 1983's Born in the U.S.A., which took the Official Albums Chart number one seat with over 1.6 million albums sold.

When the choir first came together last summer, I bet none of them believed they would be chomping at The Boss's heels in the charts within the year, said Talbot. If it were a movie script, you wouldn't believe it.
