Q,

Just realised I missed the last verse of Owl lullaby:

With your head on your pillow, while dreams around you mellow,
And shadows are forming upon your walls,
You're all lost in slumber, while I sit and wonder,
Who, who, who?

Finish:
Who knows the reason why? Who can tell me why?
Who,who, who?

Sang it at at an old folks retirement home today - they loved it.
