ExUCS
Formed in about 1974, ExUCS was “a handful of friends from MonUCS, MUCS and SCUNA-or-was-it-SUMS”, who had ceased to be members of university choirs, but who still wished to maintain some links to the IV movement. While not officially members of AICSA, members of ExUCS could be sent copies of Erato and be kept informed about IV festivals. It is not known for how long ExUCS was in existence.
