The remaining dates on Yes Yestival Tour with Todd Rundgren and Carl Palmer's ELP Legacy have been scrapped following the unexpected death of guitarist Steve Howe’s younger son, Virgil. 

The tragic situation was explained in a brief post on the Hall of Famers’ website, though details surrounding Virgil’s death were not disclosed.

The British prog-rock masters, which currently features a lineup of Steve Howe, Alan White, Geoff Downes, Jon Davison and Billy Sherwood, “want to thank all their fans for their support and understanding at this time,” a statement reads. “Steve Howe and family ask for their privacy to be respected during this difficult time."

Ticket refunds for the affected tour dates -- in Moorhead, Cedar Rapids, London, Rochester, Boston and Huntington -- will be available at point of purchase, according to the post. 

Virgil, drummer for British power-rock outfit Little Barrie, played behind the kit, sang and performed keys on his father’s 1993 album The Grand Scheme of Things.  Little Barrie released a fifth studio album Death Express on July 7 via Non Delux. 

Howe’s other son Dylan, who's worked with him on many of his solo albums, including The Grand Scheme of Things, has been a part of the summer Yes shows, which kicked off Aug. 4.

After doing a few years of full-album shows, this time out Yes have been mining the group's first nine albums -- 1969's Yes through 1978's Tormato, with at least one song from each.

Yestival Tour was the band’s first full-scale outing since its induction in the Rock Hall class of 2017.
