Gregg Allman On His Marriage To Cher And New Book (Video)

Musician Gregg Allman, 64, recently went from writing in his journal to penning his book "My Cross To Bear."

Allman revealed to Good Day NY what his biggest regret was when The Allman Brothers Band were inducted in the Rock and Roll Hall Of Fame in 1995. The musician also tells the story behind where he wrote the hit "Whipping Post." (Hint: it's on an unlikely surface.)

Newly engaged -- his 24-year-old fiance is his seventh wife -- Allman opens up about his marriage to Cher, and why it ended nearly three years later. Want to know what happened? Check out the video above.
