Thomass the Tank Engine.
There's two, there's four, there's six, there's eight.
Shunting trucks and hauling freight.
Red and green, and brown and blue.
They're the really useful crew.
All with different roles to play around Tidmouths shed so far away.
Up the hills, and round the bends.
Thomass and his friends.
(That's all of the song I can remember.)
