<p>This is somewhat off subject, but....</p>
<p>I have had zero experience with a capella groups, either personally or through S and D. However, last spring while in Miami for a conference we were walking around the street "mall" where all the outdoor restaurants are (can't remember the name) and were entertained for about 1/2 hour by a wonderful a capella group. Many people listening put money into the hat when they passed it around.</p>
<p>I got to talking to one member of the group and they were from a school in the northeast on spring break in South Beach and were singing for about 1 hour per evening to jointly finance some of their spring break activities. Two things struck me - one, that they all liked each other enough to travel on spring break together and two, they were very good</p>
