Quite an event!

Today's song must be one that reminds you of an event.
When my son was born, after a couple days hooked up to machines, he was transferred to my room for the night. I was left alone with this little man and wanted to sing him something soothing, but no lullaby came to mind. I drew a blank, and out of nowhere I started singing Good Riddance by Green Day (incidentally my hubby's favourite band). I soon brushed up on kiddie songs but to this day, when I hear the song, it reminds me of singing it over and over that one night...
And here it is for your listening pleasure!
