Big hotel with a light on, don't care if you're too far away...

The story:

When I was driving with my family, we were listening to the radio. The song comes on and my Mom started singing along. When she sang the "correct" words, I asked.."are you singing the right words?" She said yes. I told them what I thought it was, and they were laughing so hard and for so long, they were all practically crying. That was about four years ago and I haven't lived it down since. When my family thinks about it now, they still laugh!
