WOW! an incredibly powerful and emotionally stirring voice. his guitar playing isn't too shabby, either. he has personalized the song to reflect his youth (WARNING: contains profanity). apparently, back when this video was made, dave was a homeless man who went by the name "mustard". more recent videos show him as a street performer in Stockholm. incredibly, most people walk past him without as if, he's not there. videos of him performing "zombies", "angels", and "brown eyed girl" to name a few songs. all are exceptionally fine and well worth a listen.
