Afternoon of the Rhino if I remember used to be played quite closely with Night of the wolf, at I think, Bradford (Queens Hall) Many, many years ago, and I used to get the two mixed up
Not into instrumentals too much, as I prefer a good old heartbreaking vocal..... but they do sound like TV show themes from the 7ts, bet they would have been used in the "love boat" at sometime or other or what was that other programme, had that little guy on it Tatoo who said "the plane, the plane"
