"The Tailor and the Mouse" (Roud 16577) is an English folk song.
There was a tailor had a mouse
Hi diddle um come feed-al
They lived together in one house
Hi diddle um come feed-al
Chorus (after each verse)
Hi diddle um come tarum tirum,
Through the town of Ramsey,
Hi diddle um come over the lea,
Hi diddle um come feed-al
The tailor thought his mouse was ill
Hi diddle um come feed-al
He gave him part of a blue pill
Hi diddle um come feed-al
The tailor thought the mouse would die
Hi diddle um come feed-al
He baked him in an apple pie
Hi diddle um come feed-al
The pie was cut, the mouse ran out
Hi diddle um come feed-al
The tailor chased him all about
Hi diddle um come feed-al
The tailor found his mouse was dead
Hi diddle um come feed-al
So he bought another one in his stead
Hi diddle um come feed-al
