Hi Tom.
No-I don´t know the full song. I used to but it has been a loooong time since I practiced this run. But it is a great run to get use to outside picking and some position shifts.
And thanks for the comment on the improv. My main focus the last year has been on some technical issues with my picking and recording with my band so haven´t really improvised a lot. Think I will do that some more in the future.
