Has there anyone out there from Hampshire or the Southampton area any recordings by Roy 'Cobblers' Harrison of Mike 'Guttapercha' Sadler?

Roy died about twenty years ago, and I have a poorly recorded cassette which includes the immortal 'These boots were made in Woking.'

I am in touch with Mike Sadler whom, I was told no longer performs, and wondered that, apart from the recordings by both made on Forest Tracks, is there anything else privately or publicly available.
