English progressive rock act Yes will celebrate its 40th anniversary with a 26-date North American amphitheater and arena tour, beginning July 12 at Canada's Quebec City Festival, and wrapping Aug. 22 at the Gibson Amphitheatre in Los Angeles.

Tickets for the "Close to the Edge and Back" summer trek, produced by Live Nation, will go on sale March 29 via LiveNation.com. Along with the upcoming jaunt, Yes will commemorate its 40 years with a live album. Details are still being worked out, but the album could be released this summer, according to a spokesperson.

The trek brings Yes back into the touring fold for the first time in four years. The band's current lineup includes founding vocalist Jon Anderson and bass player Chris Squire. Joining the musicians are Steve Howe, Alan White and Oliver Wakeman, who is the son of former Yes keyboard player Rick Wakeman.

In collaboration with the summer tour, VH1 Classic will hold an online contest in April to give one fan the opportunity to perform onstage with Yes on "Give Love Each Day," from the 2001 album "Magnification." Participants will be asked to upload a brief musical performance video to vh1classic.com. Anderson and a VH1 Classic panel will choose three finalists, and online viewers will select the overall winner.
