When playing the chorus for the second time; play A as an open
string instead of playing the C string open the first time,
it's a bit fiddly but if you listen you can hear it.


When it comes to end of the chorus before the bridge,
keep repeating the G picking pattern and make the transition
into strumming (listen to song for correct timing)
