Peter (on the right with his knee on the amp) came across this pic taken in 1964 on the occasion of Sarah's coming out party (I wouldn't have said the dress was that low-cut). She is seen here with local group the Foot Tappers.(Click to enlarge)
Sarah was the daughter of Major Ruffer and the bash took place in a marquee at Stokesley.
Where are you now Sarah - the lads fancy a return booking.
