It'll be a night to "dance, romance and remember," when the big band-era radio broadcasts swing back into action this Saturday in the Ballroom of the Hyatt-Regency Hotel on Capitol Hill. It's the Washington-based "Live Again," a radio program scheduled to go into syndication in July, which kicks off a new version of an old concept. Frank Potts' JP Productions has set up the playing of the Live Again Orchestra and Swingtime Singers (featuring many of the top musicians in Washington) which will feature the charts of Charlie Spivak's Big Band. The 75-year-old trumpet-playing bandleader headed one of the popular dance bands from the mid-'30s into the early '50s and is still swinging, with a new album recently released. He'll be accompanied by vocalist, Jimmy Saunders, who is active in Philadelphia's jazz scene. Paul Anthony and Ed Walker, Washington's maestros of the Big Band sound, will host the show, the first of its kind in almost 30 years.

Potts, who says that Big Band music is more popular now than in its heyday in the '30s and '40s, "wants people to enjoy the music and the idea of Big Bands again." So "Live Again" will feature singing commercials and the classic "cigar-cigarette girls." Saturday's show is the first of a projected weekly series of concerts that Potts says will be developed around a theme with such guests as Big Band leaders Charlie Barnet, Ray Anthony and Si Zentner and vocalists Chris Connor, Helen Forrest and Helen Ward. Potts has even sent an offer to one-time vocalist for the Tommy Dorsey band, Frank Sinatra, admitting it's a "shot in the dark."
