"Whipping Post" (1969)
Not wanting to wake up his sleeping baby, Gregg wrote this landmark early Allmans song on an ironing board in the middle of the night when he couldn't find any paper. A tortured cry for help, it didn't start that way, as guitarist Dickey Betts told Allmans biographer Alan Paul: "'Whipping Post' was a ballad when Gregg brought it to us. It was a real melancholy, slow blues." That changed when Oakley worked up that famous intro and the song kicked, and Gregg's intense, at-the-crossroads delivery puts it over the top.
