Before I forget, and discard the playbill, I want to mention a fun concert I attended on April 17th at Carnegie Hall by those folks in the title. I never heard of them until I received a Smarttix email that mentioned the concert. Smarttix does ticketing for an eclectic variety of NYC events that aren't Broadway shows. I actually watched this video that was inserted in the email.
I was hooked. I talked a tour guide friend into joining me and we had a great time. These two are sort of a two man PDQ Bach show with a wider range of music. If they perform in your part of the world go see them. (I somehow doubt that Joshua Bell and Billy Joel will be part of the encores at other performances).
