Thanks for the background on Google, candy. I knew the song (or bits of it, anyway) but didn't know it's date or provenance. It has helped me to date the musical chair to 1926, which was the year my eldest brother wsa born and so was undoubtedly a christening gift. The chair, unfortunately, succumbed to woodworm and the musical box to rust, so I no longer have it.

I'm immortal until proven otherwise
