Got to correct that, Ka Kui taught Ah paul guitar... Paul only had the basics... Ka Kui taught him the technical details and such.
I am one of those who grew up listening to Beyond... from their 5 man days with the keyboardist / Guitarist to the 4 man days.. till 3.. I still collect thier individual solo albums... Each of them had thier own individual style, can see that the drummer Ah Wing though cant sing very well has improved quite alot..
Oh did you know Ah paul is i think the only asian artist to be endorsed by Ovation? he has an ovation signature series.
Wow u must haven been a fan for 25 years, from their 5 man band to their individual solo albums, for that I give you a standing ovation.
I am not sure about the teaching part though, havent heart of it, doesnt matter anyway.
