"We just wanted to give it an updated look," Freeman said.
He said the new photo came from the album's original photo shoot. The CD's booklet includes a couple of other previously unreleased outtakes from the session, as well as images from the first release's album jacket.
The LP's original cover art also is included, under the CD's clear tray.
Byrd's recordings were originally released in 1978, during his first stint as U.S. Senate majority leader from 1977 to 1981. Barry Poss, the eventual founder of Sugar Hill Records but then a graphic designer at County Records, was chosen to produce the album.
Freeman said Byrd started putting the songs on tape in a northern Virginia recording studio, backed by top bluegrass musicians and Country Gentlemen members Doyle Lawson on guitar, Spider Gilliam on bass and James Bailey on banjo.
Byrd played his fiddle and sang traditional tunes like "Turkey in the Straw," "Rye Whiskey," "There's More Pretty Girls Than One" and "Will the Circle Be Unbroken."
But recording didn't go very well at first, Freeman said.
Intimidated by the professional studio surroundings, Byrd's nerves got to him and his performances suffered, he said.
The session's recording engineer suggested taping the performances in a more comfortable setting, so the entire operation - recording equipment and all - moved to the senator's Capitol Hill offices.
Byrd started fiddling as a teenager and performed in several square dance bands. After his political career began, he frequently used his musical talents to entertain crowds at campaign stops and other events. He also appeared on the "Grand Ole Opry" and "Hee Haw," alongside country music legends like Charley Pride, Roy Clark and Barbara Mandrell.
He lay down his bow in 1982 after the death of his grandson, Michael Moore, when tremors in his hands worsened.
Although Byrd has rosined his bow for the last time, his fiddling is becoming increasingly popular.
"The phone's been ringing off the hook since Monday," Freeman said.
