My mom bounced many babies including her own on her knee to this rhyme. She was born in Belfast in 1944 and sadly passed away here in Canada last November (2009).

Her version was:

Chip Chip my little horse
Chip Chip Again sir
How many miles to Dublin town,
Four score and ten sir

Chip Chip my little horse
Chip Chip again sir
Can I get there by candelight
You can and back again sir

I miss her so much, but I can hear her singing with me, when I bounce my son on my knee ... love u mom
