Irish Sing-Along

As I was walking down the hall, I passed a room which had five visitors in it.  They all took a synchronized “double take” as I came to the door, and they were all amazed at the harp.  They requested that I play some Irish songs.  At first I thought the patient was unresponsive, but as I began to play, the visitors began to sing along.  Soon, the patient joined in as well, and by the time I finished everyone was singing and clapping, including the patient!  They all enjoyed the music very much.  As I left, I heard one of the visitors say to another, “What a wonderful surprise!”
