Paul Osborne was chosen to turn "Picnic" into a musical in the 1960s. It was called "Hot September" and instead of going to the Alvin Theatre on Broadway in October 1965, the musical premiered in Boston and closed within a few weeks. Another rewrite of "Picnic", undertaken by Inge himself in the early 1970s, was titled "Summer Brave". It opened at the Equity Library Theatre in New York in 1973, two months before Inge committed suicide. The play only lasted 14 performances, but it was revived two years later at the ANTA Theatre. This time it lasted 18 performances.
