Since people have started asking for facts rather than assertions, here's a few to start the ball the rolling.

Fact. Under the royalty agreements which Kennedy drew up, 50% was split between "our informants, collectors, authors and arrangers", and the remaining 50% was claimed by Kennedy. Source. Folk Review. March 1974.

Fact. When Geoff Wallis asked Kennedy for permission to use some recordings for a non-profit making CD, Kennedy asked him for 75% of the retail price ! Source. This thread. NB., I have seen the correspondence Geoff refers to. I have also seen Kennedy's grovelling response when Geoff pointed out that the recordings were almost out of copyright and would shortly be available at a much less extortionate rate elsewhere.

Fact. The collector, Tom Munnelly once sent a tape of the singer, John Reilly to Kennedy for interest purposes only. Without consulting Munnelly or Reilly, and without paying a red cent in royalties, Kennedy published the tape in Folktrax. Source. The IRTRAD_L discussion board.

Fact. In 1979, Keith Summers attempted to record Maggie Murphy of Tempo, Fermanagh. (She had previously been recorded by Kennedy when she was still Maggie Chambers.) She was extremely reluctant, saying that Kennedy had got her to sign "a piece of paper", assigning not only the songs he had recorded from her but any she might remember in the future. Source. A lecture which Keith gave in Hermitage, Berkshire, in May 1984., plus a copy of that lecture which I have in my possession.

Fact. Folktrax products fall way below anything resembling acceptable standards. They were copied onto poor quality cassettes, using recorders which often sounded as though the heads were badly in need of cleaning. And the notes consisted of single sided A4 photocopies - often illegible. Source. Take a look at a few. N.B. I once bought a tape of Yugoslavian music from Kennedy. The tape had already been used to record some English folk duo or other. It hadn't even been wiped before the Yugoslavian music was dubbed on.
