disagreed with the notion that Dudek co-wrote the song, noting that Betts created the melody of the song and its rhythm. In contrast, Dudek claims Betts walked with him into manager Phil Walden's office, demanding he receive songwriting royalties for Jessica. "I didn't understand all that exactly at the time, but in retrospect, I should have got 50 percent. Because it wasn't a completed song until I gave him the bridge section, the part that goes to the G chord," remembered Dudek. Drummer Butch Trucks questioned Dudek's account, noting that they all spent time crafting the arrangement. "I wasn't there, so I can't say what Les did or didn't do, but I take that with a grain of salt. Look at the track records of what each of them has written besides Jessica. I think it could be a group credit almost, and if any one person would have a writing claim it would be Chuck Leavell, who added a tremendous amount to 'Jessica'," said Trucks. Leavell acknowledged this: "I could say I co-wrote it, because I made a lot of suggestions, but I don't think that's fair." After Dudek left Capricorn Records to tour with the Steve Miller Band, he was let out of his contract, which involved no credits on the publishing deal for Brothers and Sisters. He maintains that Betts apologized to him about "the whole 'Jessica' thing" years later, claiming Capricorn said they did not have to pay him. Composition The tune is in the key of A Major, with the main guitar solo using the key of D Major. The signature melody line, as with all of Dickey Betts' instrumental compositions, is played harmonically among various instruments, in this case, Betts taking the melody on guitar, Chuck Leavell playing the top harmony line on the Fender Rhodes electric piano, and Gregg Allman playing the bottom harmony line on the Hammond organ. Leavell also plays grand piano on this tune, playing a solo, for over a minute, from around the 2:30 mark. The acoustic guitar is played by Les Dudek. The original version on Brothers and Sisters clocks in at 7:30, although there is a shortened single edit, which cuts out some of the main theme at the end of the piece, trimming it to 4:00 exactly. This version is the one heard on most classic rock radio stations, and any kind of various artist compilation
