Okay so it’s not exactly Spinal Tap but it’s about as close as it’s going to get.

According to the website, unwigged.com, Christopher Guest, Michael McKean and Harry Shearer are leaving the costumes and wigs behind but will play the music of their cinematic alter egos, Spinal Tap — as well as the Folksmen from A Mighty Wind — on a 30-date concert tour this spring.

The tour will open April 17 in Vancouver at the Centre For The Performing Arts, come to Toronto on May 21 at Massey Hall.

The six-week theatre trek, dubbed Unwigged & Unplugged: An Evening with Christopher Guest, Michael McKean and Harry Shearer, runs through May 31 in Milwaukee.

Tickets go on sale Friday in Vancouver and on March 12 in Toronto at ticketmaster.ca. Local on-sale information has yet to be officially announced.

The shows’ repertoire will be drawn from the two Spinal Tap albums — This is Spinal Tap (1984) and Break Like the Wind (1992) — as well as the soundtrack to the Guest-directed A Mighty Wind (2003).

According to billboard.com, at a press conference in L.A. on Monday, Guest, McKean and Shearer played a short set that included Spinal Tap’s Hell Hole and Sex Farm and Old Joe’s Place from A Mighty Wind.

Billboard.com reports also the trio is in the midst of recording a new Spinal Tap album that will be released May 26 and feature the “original studio versions” of the live songs on This is Spinal Tap and some new songs — including the ironically titled Short and Sweet, a 20-minute epic to which they’re adding a guest guitar player.
