@bbarten Original Capricorn releases on CD from the late 70's tend to be hard to find. However, there's a label in the UK called BGO Records ("Beat Goes On") that have released remastered CD versions of a few albums by former Capricorn artists like: The Dixie Dregs and Sea Level.
It is easy to get on their email list; and, it's also easy to send them an email with suggested releases. I'm kind of surprised about "Children of the Sun" never getting remastered and re-released.
