We're all going on a summer holiday

This song has been running in my mind (on and off) for several weeks now. Seeing as we are actually on one of our short summer holidays just now I thought I'd bless you with a memory of mine. My mum shared this movie with me when I was younger. It came out in '63 when she was a teenager and already seemed pretty old when I saw it in the early to mid 80s. But the music is great! I'd love to see the whole movie again.
