that's cool graham...me & my mates in 'Pinas always sing that thingy in videoke we had a mobile system at home. from the 80's my brothers run a mobile sound sytem for hire like disco's/ fiesta's/ xmas parties to schools & companies to north & sound of Cebu even reach Leyte. But when they got married, we sold some of our 12 bigs speaker box & some mobile sound equipment. We maintain a few for our personal use like disco lights, music box & speakers....So at home, we always have this full blast sounds glad the nieghbours didn't throw us tomatoes
