Can anyone tell me (or give me a URL) where I can find the source of the original broadside of George Spicer's 'Folkestone Murder' song?
This is the one that starts: 'Kind friends, come pay attention, and listen to my song ...'
This version is predominant in south-east England and efforts to locate the original has been fruitless. (There are two other versions in Julia deVaynes's 'The Kentish Garland', but are nowhere near the one under question).

I am trying to bridge a 15 year gap between the time George's father-in-law was born in 1874 from whom George learnt the song, and the murder itself. (Pedantic, I know, but authoritative if a successful match can be identified).

PS:- Yes, I have tried other ballad websites, and also Steve Gardham, and it's eluded him as well!
