Ed Miles; Courtesy of Fairport ConventionLed Zeppelin‘s Robert Plant makes a guest appearance on the upcoming album by Fairport Convention, 50:50@50, which celebrates the British folk-rock band’s 50th anniversary. Plant lends vocals to a rendition of the vintage spiritual tune “Jesus on the Mainline,” which was recorded at a concert in Banbury, U.K.

According to a message from longtime Fairport Convention bass player Simon Pegg posted on the band’s official website, 50:50@50 features half studio tracks and half live performances recorded at various U.K. shows, including at the band’s annual summer festival, Cropredy.

Plant’s connection to Fairport dates back to 1971, when he duetted with the group’s then-lead singer Sandy Denny on the Led Zeppelin song “The Battle for Evermore.” Robert also performed with Fairport at the Cropedy Festival in 1986 and 2008.

50:50@50 is scheduled to be officially released on CD and digitally on March 10, but pre-release copies can be purchased now at Fairport Convention’s online store. You also can check out clips of each track on the album at the site.
