Happy birthday to you Son, Have many, many more.
May lots of these good wishes, be landing at your door?

I wish health, wealth and happiness to you for many years
Surrounding you and everyone, repelling any tears

When you were young I got it wrong, I’d no book on being a Dad
It’s not an easy job as you know, to help raise a little lad

I’m not an expert now you know, it isn’t really fair
All that I can tell you, is that deep inside I care

I don’t mind admitting it and I could shout it out quite loud
I love you now and always Son and I’m very, very Proud

Happy Birthday to you Old Son, I hope things aren’t too Bad
Many, Many Happy Returns to you from your Old Dad
