The riff for Ramblin' Man?

Does anyone know the riff in The Allman Brothers Band's song, "Ramblin' Man"? It's the guitar part that is first played by itself in a "call and response" pattern with the lyrics "Lord, I was born a ramblin' man," then as a lead, then in the last half of the song, it's played over and over while another guitar solos (in E minor pentatonic from a tab I saw, if my meager theory knowledge serves me right) over it. I'm only looking for this one repetitive lick. Any help would be much appreciated!
