DO "Back when I was a roadie for Merle Haggard, we were tourin' with Willie -- Nelson that is -- and Willie'd locked himself in the bathroom of Glenda, that's what we was calling the tour bus at the time, and wouldn't come out. So Merle starts hollerin' at him, saying, 'I told you not to take the yellows and the blues at the same time,' and causin' a big fuss. But we had a gig to play, and Merle just left him locked in the bathroom all night, and went and played his usual set. When we came back after the show ,Willie was just a-smokin' like his usual self, like nothin' happened, and he was playing this new song he was calling 'On the Road Again.' Blew my mind, man."
