“The American Revolution,’’ Bill Lichtenstein’s long-gestating documentary about radio station WBCN, isn’t finished. That’s the bad news. The good news is it’s close. Monday, Lichtenstein and a legion of Boston rockers are getting together at the House of Blues for a fund-raiser they hope will put the project over the top financially. Party-goers will get an early glimpse of footage from the film along with photos and other archival material gathered by Lichtenstein during production. (Fans who donated $104 to the film’s successful Kickstarter campaign last year get free admission, but tickets are still available at www.Kick startWBCN.com.) Among those set to perform Monday are Tom Rush, Livingston Taylor, Jonathan Edwards, and “Spider’’ John Koerner. Also on the bill are former members of the band Boston, Billy Squier, the Uptown Horns, Danny Klein of the J. Geils Band, Peter Case, Jon-Pousette Dart, Kate Taylor, Willie “Loco’’ Alexander, the James Montgomery Band, The Fools, Sandy MacDonald, Johnny A., Tosh1, Barbara Holliday, and members of Duke & the Drivers and Barry & the Remains. Handling the host duties will be — who else? — Charlie “Master Blaster’’ Daniels, the emcee at the legendary Boston Tea Party. Lichtenstein, a journalist and documentary producer whose broadcast career began in 1970 — at the age of 14 — with a job at WBCN, has been working on “The American Revolution’’ since 2006.
