I've been in touch with John recently -

The Broadsheet King The Hermitage 89 Harmood Street London NW1 8DT

He is still active but ageing - he has at least 2000 assorted pieces of ephemera and some unbound copies of Ashton's "Real Sailor songs" - £25.00 - inquire if you are interested. There are also separate sheets from his version of Hindley's "Curiosities of Street Literature." and copies (whether bound or not, I do not know, at £40.00.)

For £2.00 he will send you an envelope containing various pieces of printed ephemera of his own manufacture - some songs, some squibs and jokes. This he calls the "Gallimaufrey"
