For Summertime, Mimi Allen had one in the old Salvi Pop Series that had a shorter version for lever harp and a longer one for pedal harp. I don’t think it’s still available as a single sheet but it’s in one of the collections of those pieces.
Also, Louise Trotter has both lever and pedal arrangements. I haven’t seen them, but I’ve seen her play the lever harp version and it’s probably easier than Mimi Allen’s.
Paul Baker also has a pedal harp version, which is published by Vanderbilt, but I don’t know anything about what it’s like.
