I booked Heart and Soul for my wedding!! If it means anything, I am a music teacher, and so is my mother - so we are definitely very critical. We both LOVED them. THe lead singers are excellent and they do the current music extremely well, which was important to me! Good Luck - i definitely recommend and my fiancee and I saw 8 bands! Let me know how it goes!
AviDon was referred to me by two separate people, and I have seen one person's proofs, and thought they were beautiful. Price-wise, he is a little high, although we didn't shop around after finding him, so he may be in-line with other photographers these days. I really don't know. His website is http://www.avidon.com
I'm hoping that I'll be able to get a good idea from that of who's coming. One of the hotels has a cut-off date of 3 months prior to the wedding, so we had to get the info out well in advance.
