Gregg Allman's manager on details of singer's final days, album

He says in the end, Allman was at peace.

As it became clear that Allman was dying, "[W]e started talking about preserving his legacy, and especially the new record, Southern Blood -- that made him light up," Lehman told Variety.

Allman began work on the album more than a year ago with producer Don Was in the legendary Fame Studios in Muscle Shoals, Alabama. Lehman confirmed that Allman was "struggling a little with the recurrence of his liver cancer," but worked around his health problems to record the new album.

"He and Jackson were in communication a lot because they were working on 'A Song for Adam,' and Jackson wanted to be there for Gregg," Lehman said.

Lehman said that, in the end, Allman was at peace.

"He’d listen to music, read books, see his kids," Lehman said. "He got married to Shannon in February so he was able to take advantage of that time with her and being at his house, sitting by the pool, playing with his dogs."

"Thank goodness he did not suffer at the end," he said. "He died peacefully at home."
