It’s fun to try doing the ending backwards… 

Down down baby, down by the roller-coaster
Sweet sweet baby, I’ll never let you go

Shimmy shimmy cocoa pop
Shimmy shimmy POW!
Shimmy shimmy cocoa pop
Shimmy shimmy POW!

Grandma, Grandma, sick in bed
She called the doctor and the doctor said

Let’s get the rhythm of the head, DING DONG!
Let’s get the rhythm of the head, DING DONG!
Let’s get the rhythm of the hands, (CLAP CLAP)
Let’s get the rhythm of the hands, (CLAP CLAP)
Let’s get the rhythm of the feet, STOPM STOMP!
Let’s get the rhythm of the feet, STOPM STOMP!
Let’s get the rhythm of the HOT DOG!
Let’s get the rhythm of the HOT DOG!
Put it all together and what have you got?

DING DONG
CLAP CLAP
STOMP STOMP…HOT DOG!
