While at the Seattle Opera's "Marriage of Figaro" performance, I noticed in that the program listed Ted Botsford as the assistant principal bassist. Since the Seattle Opera regularly draws its orchestra from the Seattle Symphony roster, I took at look at the Seattle Symphony's web site and found Botsford listed as a member of its bass section here. As with some former members of the Oregon Symphony, Botsford has moved to an orchestra that pays more, but it is also a tribute to the fine playing of the OSO orchestra. Since Kalmar's arrival, several instrumentalists have won auditions at other orchestras (for example, the Boston Symphony, the Baltimore Symphony, the Detroit Symphony, and the San Diego Symphony).
So, this is old news, in a way, but Botsford is still listed in the Oregon Symphony programs as on leave. I understand that the designation is a formality due to union rules.
