Lyrics:

It's Johnny's birthday, it's Johnny's birthday
And we would like to wish him all the very best
It's Johnny's birthday, it's Johnny's birthday
And it's so nice to have you back, so be our guest
At Johnny's birthday, at Johnny's birthday
We'd like to wish you all what you would wish yourself
On Johnny's birthday, it's Johnny's birthday
And it's so good to have you back from off the shelf
And it's so good to have—
Back from off the shelf
