A few of mine are:
Sailing by Rod Stewart
Hold Me Close by David Essex
Who Loves You by The Four Seasons
I Only Have Eyes For You by Art Garfunkel
Plus a load of dreary autumn-themed school hymns and children's songs, e.g. The Rainbow Song (red and yellow and pink and green etc) and something about speckled frogs sitting on a speckled log eating delicious bugs. Probably taken from the Apusskidu songbook.
