Okay, I'm wee bit confused by dates.
The Queen Concertography site and Queen: The Early Years both have Johnny Quale leaving The Reaction in the autumn of 1965. Before that, according to The Early Years, JQ&TR (with Roger as a member) recorded "a demo disc" at a cinema in Wadebridge, by a primitive mobile studio. Johnny Quale, quoted in the book, says a dozen discs were made of this session, but has no idea what happened to them. Shortly after, JQ left.
Now, Record Collector mag, Feb. 2000, lists the follow Reaction acetates, dated 1966.
1. What's On Your Mind / I'll Go Crazy / Bona Serra / Just A Little Bit
(by Johnny Quale & The Reaction, Sound Studios D 105 10, UK 7" Metal Acetate, 1966) - £1,500 +
2. I Got You / In The Midnight Hour
(by The Reaction, Sound Studios 105 11, UK 7" Metal Acetate, 1966) - £1,500 +
How is Johnny Quale to be credited on a 1966 recording when he left in late 1965?
Which piece of information is flawed?
