I think like a great many of the records under discussion here it might have got the odd play at Wigan, the Mecca or St. Ives etc. but someone didn't really get behind it 'til the post-Stafford era.
Records were definitely coming to have a longer shelf-life around this time if they were good. The quick turnover of sounds at Stafford was replaced by certain records being featured heavily for months or even years in certain playlists. I can think of a period of time lasting about ten years where it seemed impossible to go out and not hear, for example, The Trannells played by a couple of deejays. That's not a criticism, by the way, just the reality that if something was good and genuinely rare it was worth persevering with, and that while great records were and are still being unearthed, it was an illustration of the law of diminishing returns.
The dedicated record-hunters were and are becoming a smaller group: maybe you can count them in the tens these days when in the past (say at Wigan) there were literally dozens of people who could point the top deejays in the direction of fantastic unknown tunes.
