It’s nice of the man to entertain the old folks with songs that are 50-something years old. It’s a lot like one guy at the mic at karaoke. And he gets brownie points for memorizing the lyrics. I like to do karaoke but I don’t have the lyrics to the songs memorized - so I’m not going to tell you that I’d do any better than the maestro.
Filipinos love to sing karaoke at home, so the staff loves this show, too.
