I bought a ticket (three tickets, actually) to take the Motown Museum tour and bought a $30.00 James Jameson t-shirt in the gift shop, which got me a free copy of Barry Gordy's autobiography). If you're just a tourist, hey, serves you right, but if you know some of the details about what you're seeing, it's money well spent, believe me. I was moved to almost-tears when entering The Snakepit. Good god....
I hope that Claire Daly has done something similar, or else is planing on it. Those records, hell, that music in general) is at least as fundamentally American as the so-called "Great American Songbook".
