Wish You Were Here [1/4] by Pink Floyd
This is one of the all-time great guitar songs. It has a fantastic intro and the whole song is great fun to play and a surefire campfire classic to get people singing along!
The intro is a little tricky and will take some pick accuracy and some good rhythm skills if you want to play it in time, properly. Worth taking the time and getting the timing right - it makes all the difference!
Beginners will probably want to start off with the Verse and Chorus (Part 2) strumming parts which are considerably easier!
