Played keyboards on the title track of Yes' "Open Your Eyes" album
(1997). He also played with them on their "Union" album (1991) and well
as touring the USA with three members of Yes in summer 1992 as "The
Chris Squire Experiment".
Played keyboards and synthesizers for the band TOTO, and other background groups.
The Toto song "Rosanna" is incorrectly assumed as using Rosanna Arquette name who was dating Steve then. David Paich wrote Rosanna and needed a female name so Steve's girlfriend was just chosen.
