Dave Prager joined on bass in the spring of 1989 and did not take a name.
It was raised. According to Wisniewski it was raised twice, across two rehearsals, and then it stopped being raised, because Dave's position did not move and because he was better than the bass player they had before.
He appears on all three records, on every sleeve, on every poster, and in the parish register, as Dave.
Nobody in the band has ever explained this and nobody has ever apologised for it. Asked about it in 1994, Quill said that Thaddeus-upon-Avon is a real village and real villages contain a Dave.
He is the only member the archive has been able to locate. He answered on the second ring, confirmed the dates, corrected two of them, and declined to discuss the village on the grounds that it was not his to discuss.
