About 20 years ago I sang in an a cappella group. One of the songs we sang was the Boyz II Men song, "It's So Hard to Say Goodbye to Yesterday," which is a song about the end of a love affair. One day we sang a concert at a retirement home and we included that song on our set list. About halfway through the song we realized that it was a really bad choice for a retirement home concert. Lyrics like, "If we get to see tomorrow," and "I thought we'd get to see forever but forever's gone away," have a really different meaning.
