London -- On a recent Sunday night, an enthusiastic audience watched a concert performance of "By Jupiter," the 1942 musical by Richard Rodgers and Lorenz Hart. A neglected work, but one created by what Ian Marshall Fisher, the concert's impresario, calls the "creme de la creme of musical theater writers."
After three acclaimed seasons, "Discover the Lost Musicals" has moved to the 280-seat Cinema One.
In November, if Mr. Fisher gets the cash, he hopes to take his concert versions of two such "lost" American musicals to the Smithsonian Institution in Washington.
