Howard,
Glad you like it. I just wish that Amazon had more decent ballroom titles. When we have squeezed as much music out of them as we possibly can, I'll probably break down and become a full-fledged reseller of ballroom music, complete with on-line credit card ordering.
I'm told that 30 seconds is all I'm allowed to play. Normally if a song has a really long intro, I clip it out. But if it's short enough, I don't bother. My rule has been about 8 or 10 seconds max length for an intro, but I can shorten that.
Sincerely,
Jonathan Atkinson, www.ballroomdancers.com
