The Dirt Band & Steve Goodman
The Dirt Band has a long career which has crossed many genres of music from folk to rock to country and then back again. They appear on the album "A Tribute to Steve Goodman" and also recorded four of his songs in their career.
To say Goodman influenced them would probably be stretch. More likely Goodman and the Dirt Band were just traveling down the same road.
Jimmy Ibotson collaborated with Steve On "Face On the Cutting Room Floor".
