When my kids were babies (hmmm, maybe 1 & 2?), we used to sing - scratch that - I used to sing this song...

High in a tree a dickie bird... (sat)
Below him sat a furry black... (cat)
He said for dinner I shall have... (you)
Then all at once that dickie bird... (flew)
Bim solla bim bam

Bah solla do solla dim

Auntie Sharon taught it to us, and it was a hit! It was a catchy tune, albeit a little crazy. Fast forward a couple of years, and my boy remembers. I was shocked. Here is video of Auntie Sharon and Mac singing the bim solla song tonight. Warms my heart.
