In the fall 1999 season, Broadway will host a double dose of swing-based musicals with the opening of the Squirrel Nut Zippers' Contact at Lincoln Center's Mitzi Newhouse Theatre Oct. 7, and the musical revue Swing!, starting previews Nov. 2 at the St. James Theatre. Canadians, however, won't have to travel to the Big Apple for theatrical Big Band sounds; Toronto will be home to two Canadian limited- engagement Swing shows, Forever Swing and Swingstep.

Forever Swing, which is somewhat based on Swing! , the musical revue that is playing a 26 week stop at Vancouver's Stanley Theatre, will run Sept. 30-Nov. 14 at the Winter Garden Theatre with an opening Oct. 13. Set in the late '30s and early 40s, Forever Swing is the story of the fictitious Tommy Vickers Band, a group of musicians traveling North America, who head off to Europe as World War II erupts. Dean Regan is Forever Swing's creator.

Tauropro Entertainment/Lutvick Productions International and Rogers Communications, Inc. will produce. Tickets for Forever Swing are $69-$20 and available by calling Ticketmaster at (416) 872-5555.

The second Swing musical will be Swingstep, running Oct. 3-Nov. 28 at the Apotex Theatre in the Ford Center for the Performing Arts. With the collision of two different dances, swing and traditional Scottish Stepping, Swingstep is what happens when Sonny Stone, a New York City Swing musician, comes to his grandmother's deathbed in her hometown of Cape Breton. There he meets the man she fell in love with 60 years ealier and a style of dance he has never seen before.

David A. Ballinger of Silve Fox Productions will produce. Tickets to Swingstep are $70-$24 and available by calling Ticketmaster at (416) 870-8000.
