That C shape has been a staple since the Yes Album - last section of Starship Trooper. I dug out Ed Schaum's transcription of the solos for those that want to give it a go.

More fun with shapes!

I remembered there was a Steve Howe Starship Trooper/Wurm lesson out there and just found it - what's cool is how he drops his ring finger off the C shape to play the 5th instead of the root. Take a look.

I also noticed his strumming hand just maintains that beat!
