big bent records

The label that released the John the Postman stuff was Bent Records. I think you're getting confused because the catalogue numbers used the prefix BIG. Anyway they put out a single by (fairly crap) Manchester glam/punksters V2 'Speed Freak'. Also the similarly unremarkable Notsensibles 45 'Death to Disco'. Not the most distinguished of labels, then...

Most of JTP's stuff is available on a CD put out by Overground, but you probably already knew that.

This is better:

BENT 1 V2 – Speed Freak 7“ (1978)

BENT 2 JOHN THE POSTMAN – Puerile 12“

BENT 3 TEARDROPS – In And Out Of Fashion 12“ (1978)

BENT 4 JOHN THE POSTMAN – Psychedelic Rock´n´Roll Five Skinners 12“

BENT 5 NOTSENSIBLES – Death To Disco 7“

The Teardrop were Paddy Garvey from Buzzcocks and some Fall members IIRC - can't remember what the record was like.
