Leaning on a Lampost

I'm currently meant to be practicing ABBA's 'Slipping Through My Fingers' on piano - but tonight I wasn't feeling that - so I sacked it off and played rather more jolly songs (using the piano in keyboard mode - which i can play to a much higher standard), to match my mood...

One of my favourites in this particular book is 'Leaning on a Lampost' - a song from a musical that I love and that for various reasons, is quite special to me.
