I attended a Baptist service some months back and they displayed their hymn lyrics on a screen, and I was surprised to see the name Jehovah. I was not aware that they used it in songs.
It was a strange feeling, being a Witness and attending this service in a clandestine manner, and seeing the name on the screen.
Incidentally, while I liked the service somewhat, with its casual dress and informal setting (not to mention people actually playing the songs on keyboards and guitar instead of the pre-recorded songs used at JW meetings) I didn't care for the sermon much, which was overly long and placed emphasis on going to hell if we don't get saved.
