Sorry Amos and Kendall, the line is not from "Worried Man Blues." BTW, there are much better versions of "Worried Man Blues" than the Kingston Trio. The Carter Family, Woody Guthrie, Deborah Holland, Pete Seeger, to name a few. "It Takes A Worried Man" is an alternate title.As Gart T. and Banjer point out, the line does come from "Gotta Travel On," alternately known as "Done Laid Around. It's a revival era song and there are versions by, among others, the Weavers, the Kingston Trio, the Au Go Go Singers, Joe & Eddie, Bob Dylan, and Eric Bibb.
