Keystudio

Keystudio is a compilation album released by Yes in 2001. It is made up of the studio tracks from both Keys to Ascension and Keys to Ascension 2.

"Children of Light" is a different mix of the Keys to Ascension 2 track. Specifically, the Keystudio version contains an extended keyboard introduction by Rick Wakeman entitled "Lightning". This mix omits the opening lyrics found on the Keys to Ascension 2 version.

Prior to this album's release, it was reported that it would have a track called "The Second Time Around". This would have been a version of "Sign Language" that incorporated Jon Anderson's vocals. However, the track was not included on this disc.

As of 2010, the CD is out of print and regularly sells for over $50 on sites such as eBay and Half.com.
