B: What did you say? You want more singing? I will find a friend.
Narrator: B calls a friend C to join him.
B and C: Dashing through the snow
On a one-horse open sleigh
Over the fields we go
Laughing all the way;
Bells on bob-tail ring
making spirits bright
What fun it is to ride and sing
A sleighing song tonight
Jingle bells
jingle bells
jingle all the way!
O what fun it is to ride
