The Dream Theater drummer has been added to the line-up for what has been billed as the "ultimate prog rock cruise" and will serve as "music director" for an all-star tribute to Yes founder and bassist Squire.

The cruise, created by the members of Yes for their fans, will also feature sets from Marillion and the Neal Morse Band.

The third annual five-day, four-night cruise will set sail from Miami, Florida for Key West and Great Stirrup Cay, Bahamas in mid-November (15).

Squire lost his battle with cancer in June, aged 67.
