There was an interview with Thatcher in the May 2002 edition of the IHS magazine "The Horn Call", volume XXXII, number 3, May 2002, page 57. The article was written by Mark McFarland.
If you do not know of someone who receives "Horn Call", then perhaps you could find it at a University (or music conservatory) library. You could also contact IHS about whether back-issues are available - http://www.hornsociety.org http://www.hornsociety.org/HORN_CALL/index.html Jay Kosta Endwell NY USA _______________________________________________ post: [EMAIL PROTECTED] set your options at http://music.memphis.edu/mailman/options/horn/archive%40jab.org
