The gorgeous 'Summer Wind' was a track from Frank Sinatra's high-flying album 'Strangers in the Night'. Released as a single, it peaked at #25 on the US Billboard Hot 100 chart, and at #36 in the UK. It has an airy orchestral backing from Nelson Riddle and, typical of the middle-aged Sinatra's output around this time, reflected back on an earlier love from earlier years. 'Summer Wind' reached #1 on the US Adult Contemporary chart.
This was originally a German song from 1955 called 'Der Sommerwind', and an English version was released in 1965 by Wayne Newton.
