I compiled these lyrics by comparing several transcriptions found on the Internet, hence the alternative phrases:

WITH A VAMP IN THE MIDDLE
John Hartford

Make my bed with a crease in the middle
Make my home in a hollow in the hills (or "Hollywoodish hills" or "Hollywood of shills")
Make my livin' on a hillbilly fiddle
Playin' little runs and the funny (or "funky") little fills.

Well, I got me a gal from playin' on the fiddle
And the harder that I fiddle, the harder that she comes along;
And I (or "but we") gotta get happy, when we wiggle in the middle,
'Cause that's when I know they're gonna (or "I want to") come home.

CHORUS: Play, fiddle, play.
All day long, I hear you screamin' at me
Way far away in the yard.

Well, I wrote this song with a vamp in the middle,
And I knew when I wrote it, that I'd written it for the fiddle. CHORUS

[Recorded by John Hartford on "Aereo-Plain," 1971. The title is given as VAMP IN THE MIDDLE on 3 albums by New Grass Revival: "When the Storm Is Over," 1977; "Fly Through the Country," 1991; and "Grass Roots: The Best of New Grass Revival," 2005.]
