Cropredy Convention") which remains (in 2022) a mainstay of the U.K. summer festival calendar and regularly attracts up to 20,000 attendees, by no means all of whom are Fairport Convention fans. When the band reformed in 1985 they were able to embark on increasingly lengthy and successful tours and produce a series of highly regarded albums. The reason for this recording revival was partly because they abandoned the mainstream record business, instead focusing on growing their own audience and producing records independently on their own labels (Woodworm and Matty Grooves), ironically a development which the punk and post-punk era had helped to accelerate.

Robert Plant and Jimmy Page’s interest in the genre was first evident in the recording of "Gallows Pole" a traditional ballad on Led Zeppelin III (1970), which stands out among their usual output of blues orientated rock. At this time they also wrote the ballad "Poor Tom" which would surface on Coda (1982). It is more subtly manifested in their most famous album Led
