Westex, in 1975 the idea that Darrell Rhodes 45s would be $1000+ items in 2014 would likewise have been regarded as insane. The most wanted Texas records back then were probably Tooter Boatman 'Will Of Love', Sonnee West 'Rock-Ola Ruby', or David Ray's 'Lonesome Baby Blues'. Of course, there were those fantasy 45s like Andy Starr's 'Rockin' Rollin' Stone on Lin which could have existed, but time proved otherwise. Had I traded all 5 copies of 'Four O'clock Baby' for 'Rock-Ola Ruby', I would have thought it a good deal.
Forty years ago in the pre-internet age, information was hard won and jealously guarded. The Winston label was small stuff compared to Starday or Meteor. Also, 'Four O'clock Baby' was not seen as rockabilly, more white rock'n'roll - a significant difference back then. The fact that it had a sax riff running though it also reduced its desirability in the eyes of purists. A minority of old school rockabilly obsessives tended to be racists who displayed Confederate flags in their record rooms, hob-nobbed with ultra-right wing extremists and denied any black influences on rockabilly music; an unknown sax player could have been a black musician, so that ruled the record out of court.
As far as I could make out, the only collectors who had been to Mrs Moores before I showed up were 2 English characters who she did not take to and who left empty handed. A few months later another Englishman scored a few records from her, including 2 more copies of 'Four O'clock Baby'. I contacted him when I saw his ad in Record Mart magazine and he confirmed his source.
Mrs Moores never let you see the total stack of 45s; she just left the room and reappeared with a handful of records. I got the impression that she never had that many, just what her late husband had left in the garage. My knowledge of antiques helped break the ice, but instinct told me not to push, even a little bit, or the door would be shown. When I asked her about Dean Beard, she said that she had never liked him as some of the musicians he mixed with used heroin. We're talking a blue-rinsed Texas conservative lady, here.
