Benny Andersson and Bjorn Ulvaeus, the two B's in ABBA and therefore co authors on the new musical Mamma Mia!, will give a rare TV interview Nov. 6 on NBC's The Today Show. The duo had been originally scheduled for Oct. 26, but that broadcast date was changed to Nov. 6. Currently a hit in London and Toronto, Mamma Mia! makes its way to the U.S. when it opens at San Francisco's Orpheum Theatre Nov. 15. Stops in Los Angeles, Chicago, Washington, DC and Boston will be followed by an expected Broadway arrival Oct. 18, 2001. A theatre, the Winter Garden, has already been named for the show. For the U.S., the original Toronto cast, including Dora winner Louise Pitre (Donna), newcomer Tina Maddigan (Sophie), Ragtime's David Mucci (Bill Austin), Les Miserables' Gary Lynch (Sam Carmichael) and Adam Brazier (Sky), will tour, but no announcement has been made for Broadway.

Andersson and Ulvaeus were also co-authors on the musicals, Chess (with Tim Rice) and Kristina från Duvemåla.

The Today Show runs 7 AM-10 AM on Channel Four in New York City. Check local listings for times and channels.
