We went to Evensong at the Canterbury Cathedral last night. It's not the first time I have been. Though, I'm not sure it could ever get old.
First, (incredibly) it's free. Second, every inch of the Cathedral is exquisitely crafted--it's difficult to absorb such a visually stimulating atmosphere.
Then, they start singing. I wish I had words to describe how beautiful it is. All I can say is, "Go." Everyone should experience Evensong at least once; and I should go far more often than I do.
