group's producers, Harrison and Lynne directed the sessions, with Harrison often auditioning each member to decide who should sing a particular lead vocal part. The two producers then flew back to England; Lynne recalls that, throughout the flight, he and Harrison enthused about how to turn the sparse, acoustic-based tracks into completed recordings. Overdubs and further recording took place at Harrison's studio, FPSHOT, with "Sideburys" Jim Keltner (drums), Jim Horn (saxophones) and Ray Cooper (percussion). Harrison described the band's sound as "skiffle for the 1990s". The album was released on 18 October 1988. Distributed by Warner Bros., it appeared on the new Wilbury record label rather than on Harrison's Dark Horse label, in the interests of maintaining the group identity. Over the months following the end of recording in the summer, contractual issues had been successfully negotiated between Warner and the record companies representing Dylan, Petty, Lynne and Orbison. As was the case in 1971 when EMI prepared Harrison's multi-artist live album from the Concert for Bangladesh for release, Dylan's label, Columbia, presented the main stumbling block. In the album credits, the "Wilburys" joke was extended further, with the band members listed under various pseudonyms and pretending to be half-brothers – sons of a fictional Charles Truscott Wilbury, Sr. During promotion for the album, Orbison played along with the mock history, saying: "Some people say Daddy was a cad and a bounder, but I remember him as a Baptist minister." Vol. 1 was a critical and commercial success, and revitalised the careers of Dylan, Orbison and Petty. As Harrison had intended, the album defied contemporary musical trends such as hip hop, acid house and synthesised pop; author Alan Clayson likens its release to "a Viking longship docking in a hovercraft terminal". The album produced two successful singles and went on to achieve triple-platinum certification for sales in the United States. It was nominated for several awards and won the 1990 Grammy Award for Best Rock Performance by a Duo or Group. Liner notes on the album cover were written by Monty Python's Michael Palin under a pseudonym. Palin's essay was based on an idea by Derek Taylor, who wrote an extensive fictional history of the Wilburys family that otherwise went unused. Harrison planned a feature film about the band, to be produced by HandMade and directed by David Leland, but contractual problems ended the project. Orbison's death, "Nobody's Child" and
