Lyrics:

He's not a bum
Though he was a sailor
He's not bum, oh what he can build with his hands
How can you think him so bad
When he's not a bum, and he's my dad

He's not a bum
He's a heck of a singer
He's not a bum, I'm his number one fan
How can you think him so bad
When he's not a bum, and he's my dad
