Don't know that Jack the Ripper one Dave but my old friend Andrew Paige who was mentioned in another thread by Countess Richard as the author of the Woodstock spoof We're from Willesden, We're from Harlesden..... wrote a JtR song that I've not heard since 1974'ish.

The only lines I can recall are

The Police are searching high and low
They don't know who this sinner is
The found one of her feet in Leadenhall Street
And the other one in the Minories

As I only tend to see Andrew at Towersey Festival, this thread may well be as dead as one of the victims by the time I get the rest.
