GreenjackAs I learned it, there was an "And everywhere that Mary went the lamb was sure to go" after "who didn't care a little bit".
On the 16th CD in the Voice of the People series ("You Lazy Lot of Bone-Shakers")the first verse of Track 18 (Sam Bond singing, "Where does Father Christmas go to in the summertime ?") goes "Mary had a little lamb, its fleece was white as snow
And everywhere that Mary went the lamb was sure to go
It followed her up hill and dale and fields where grass is blue
Now you know where Mary went, but tell me, tell me, do
Where does Father Christmas go to in the summertime?
Goosey, goosey gander wherever does he wander?
Does he go with the ice and snow to some other clime?
Oh, where does Father Christmas go to in the summertime?
