Once Goes Broadway October 20, 2008 ‘Once’ gets musical makeover John N. Hart Jr., Jeffrey Sine and Frederick Zollo have acquired the worldwide rights to produce a legit stage version of 2007s “Once” which won the Oscar for song. Aiming for a Broadway during the 2010-11 season, “Once” is the first project announced for a new fund formed by the three producers with the intention of backing a number of stage projects. Creative team for the Rialto version of “Once” — including a book writer and a director — will be announced at a later date. Zollo said he expected both composer-stars, Glen Hansard and Marketa Irglova, to be involved in the tuner’s development, and hoped writer-director John Carney also would play a role. Musical will likely include songs from the film’s platinum-selling soundtrack along with others penned by Hansard and Irglova that did not make it into the film. In February the composers picked up the original song Oscar for “Falling Slowly”.
