In the song Clockwork Toy by Hot Club De Paris, the intro riff is played across at least two strings but the guitarist is pulling off and letting the g-string ring. It's hard to explain, but you can see it being played here:


There is a tab on UG which gives the right notes but doesn't show how to let the g-string ring. Thanks in advance.
Its not hard, use your ring finger and your pinky.

Ring finger on the 5th fret of the G string, your pinky barring the 8th fret on B and E. Either pull of the G string or stay on to let the note ring.
So to make the g-string ring after every note i have to pull off the g-string as i play each note?

Plus in the video the guitarist plays it above fret 12...
