Happy Birthday no clue

This morning was Uncle Adam's birthday. Charlotte has gotten use out of her love of singing by doing so for many a birthday. Poor kid: she's got 20 aunts and uncles and 2 great ones. So when asked for a rendition of the song for Uncle Adam the poor wee one needs a good memory to figure out the end of the line...

"Happy Birthday dear....blah blah....happy birthday to you".

And, oh, remember which Uncle Adam because there are two: Dara's and Aviva's!
