Although Eddie Calvert's was an instrumental version,
I have included the full lyrics below on request

Oh, my pa-pa, to me he was so wonderful
Oh, my pa-pa, to me he was so good
No one could be, so gentle and so lovable
Oh, my pa-pa, he always understood.

Gone are the days when he could take me on his knee
And with a smile he'd change my tears to laughter

Oh, my pa-pa, so funny, so adorable
Always the clown so funny in his way
Oh, my pa-pa, to me he was so wonderful
Deep in my heart I miss him so today
