We used to sing this at camp:

Happy birthday to Neil,

Happy brithday to Neil,

Happy birthday darling Neil...

Happy birthday to you...

Hope you live to be a hundred...

Hope you live to be a hundred...

Hope you live to be a hundred...

And then a hundred more!

Happy Birthday, sweetie. You are the most amazing, intelligent, caring and sensitive guy a friend could ever hope for. I love you with all my heart.
