Castor Cracking Group

Castor Cracking Group (CCG) was a demo group from Sweden, and were active on the ZX Spectrum during 1986–1988.

[1][2][3] They were one of the first groups for the ZX Spectrum with their release of Castor Intro early in 1986.

[4] Technically, their demos were not very advanced – they even programmed many of them in BASIC and compiled the result for release.

[4] However, their significance lies in their early entry onto the scene.

UK Lead was a label used by Castor Cracking Group for the more "serious" projects.
