Dude I just stumbled across your video for Do it again and decided to check out your channel I have to say that of all the Guitar teachers I watch your not scared to lay on the Vocals which is very helpful many teachers dont like to sing and play. I think great musicians became great by doing both. Though its fun to play its nice to know the lyrics and sing along. Which is why I say to you Hats off to you sir, you do it well.
