Singing... in the subway station

As I walked down the platform.  I hear this loud voice overpowering the volume of my earphones.  I pull them out and realize it's a man's voice singing.  Now, this is not an uncommon occurence on the subway platforms or on the subway cars themselves for that matter, but this was different.  This man had no talent and it was the song he was singing that really caught my attention.  He was belting out, "How will I know if he's thinking of me? ...Falling in love is all bittersweet."  I continue down the platform and come to a section in between where there are a ton of construction workers and find the owner of the voice.  He is on a latter, doing something in the ceiling, belting out the lyrics as they play over a mini stereo.  His fellow construction workers are dying of laughter.  I start laughing as do the people around me.  I keep walking  on the other side of the wall and see all these other construction workers standing there laughing too.  They're telling people, "he takes tips ya know."  It was soo comical, basically the best performance I've seen yet.
