I have a very delightful recording of Callum singing his own version of Jingle Bells. But, I had to convert it to a video in order to upload it, and decided to use some photos of Callum from babyhood to toddler. If you don't feel like watching, here is a partial transcription of the recording...
Callum: Jingle tiger - Jingle tiger - Jingle on the tiger
Elaine: On the tiger?!
Callum: /laughs/ Yeah! Jingle tiger - Jingle tiger - Jingle on the bubble
Elaine: On the what?
Callum: On the bubble!
Elaine: On the bubble?!
Callum: /laughs/ Yeah! Jingle bubble - Jingle bubble - Jingle on the bubble
