Name Change

My name is Billy, I've always had this name
But recent events have caused a change
In the street where I live now greeted as 'Jess'
For the life of me I'm struggling to digest
Except there was this one day back last summer
When I brought home a Dutch lady - a real stunner
If I recall rightly it was a hot and sultry afternoon
Quiet neighbourhood, windows open, back last June
Neighbours in their gardens sat eating ice cream
Gretchen came upstairs; I didn't know she liked to scream
It wasn't long 'til puffing Billy was going like a train
Then she started; sound travelling through the open panes
Oh Got! Oh Got! Jes! Jes! Jes! J E E E S !
I guess that's when I had my name changed
