Ring Around The Moon

Original score by Vic Elms and Alan Willis, recorded at Wembley on Monday 6th May 1974. Vic Elms was supposed to have prepared a score and conduct the orchestra. But Elms could not write music and did not know how to conduct. Instead he tried to demonstrate themes on his guitar. The orchestra refused to work with him, so (music arranger) Alan Willis had to take over, improvising some scores on the day.

When Koenig puts his commlock down during the interview with Alan, it features his picture on the full side of the commlock. In other shots it is a normal smaller picture.

Helena's thermograph is held up the wrong way round (so we can read her name).
