What's the source of this material. or, at least, of the Scott?
There is no information on the LP jacket but Discogs states:
"Recorded at Reeves Sound Studios, New York City; October 29, November 23 and 30, 1956." Don't know their source.
That's all I got. Maybe someone else has more.
The liner note says the session was the idea of bassist Trigger Alpert and lists Dick Hyman, Marty Paich and Tony Scott as arrangers.
On my LP, the arrangers as you give Bill are listed but nothing about the sessions being the idea of Trigger Alpert (although I read somewhere that they were). Do you have perhaps a UK version (was there such?). Mine is Jazzland JLP-11.
Mine is an OJC CD. At the end of the notes we have: "These notes originally appeared on the album liner for Trigger Happy! (RLP 12-225), a reissue of Jazzland 11." Mystery solved!
