Does anyone know what song the man in the video is performing?
Actually, he is playing "Come Sail Away" by Styx. "Para Siempre" by Joan Sebastion seems to be a blatant plagiarization of "Come Sail Away". (If anyone can shed more light on that, please comment.)
Here's the official music video of the original studio version on Youtube.
Some younger folks may have discovered this song when it was covered by Eric Cartman.
it is "PARA SIEMPRE (ADRIAN JONES)" sadly it is a bit different than homeless guy's version.
