I just received this message:

Due to security reasons related to the bombings during today’s Boston Marathon, this evening’s Boston Symphony Orchestra concert at Symphony Hall will NOT take place. The BSO will be in touch with with all patrons who were planning on attending this evening’s concert about possibly rescheduling the concert or refunds.

Sometimes this world makes me so very, very sad. My heart goes out to the families and friends of those who have been killed or are injured.
