Love is All Around by Wet Wet Wet. Yes I am aware it is a cover version but this particular version reminds me of my sister. She was about 18 months old when it came out and it quickly became her favourite song.
It also started something of a tradition of slightly changing lyrics to songs. One of the lines is “Cause on my love you can depend”. My little sister changed it to “All my loves…….” She would completely miss the end of the line. We still sing it this way to this day whenever we hear it.
