In the late 1960s, the Rosenethe Orchestra was formed, again from local music staff and pupils, to perform orchestral items as well as accompanying the choir in performances. The combined choir and orchestra became known as the Rosenethe Ensemble.
The choir continued to flourish and expand slightly in numbers but by the early 1970s, membership was by invitation and the choir was no longer formed solely from council staff or pupils. There was no subscription and no committee; George decided on a suitable repertoire for a chamber choir and orchestra and where public performances would take place.
Recitals were given mostly by invitation from churches, music clubs and other groups in Central Scotland, but on occasion other venues such as the MacRobert, at Stirling University, and the Albert Hall were used.
One particularly memorable concert took place in the Museum Hall in Bridge of Allan where the choir gave the first performance of a beautiful setting of well-known Tennyson poems by W.W. Kitchen, at that time music critic of the Stirling Observer. This work had been composed decades before, but never performed. It was a most moving occasion.
