In some of our smaller meetings on Sunday we are in rooms that do not have a piano – yet we still often sing a hymn to begin our meeting.  Our singing has actually become bearable as one of our cell phone carrying attendees started downloading the hymns from http://www.lds.org/churchmusic/ and playing them for us to follow.  He will even transpose them to lower or higher keys to better match our meager voices.  The nicer singing makes for a nicer beginning to our meeting.
