From the letter:
Our volunteers recorded more finished product than ever before: 8,646 hours. To achieve this, 425 volunteers gave 22,280.38 hours of their time in the recording studio - and this skilled work is valued at $58 per hour, equaling $1,292,262 in donated services - a record.$58 per hour? Clearly I'm in the wrong line of work, seeing as how I'm currently paid about $14 per hour. Now if I could only deduct that $2900 from my taxes!
