Here's my son doing "Spanish Fly" by Van Halen. On acoustic too instead of a classical guitar, which is a lot harder to pull off.
Be sure and tell him great job.
Pretty sure Edward tuned down about a step or so to record this. You can really hear it especially when he is doing the wide stretch hammer ons/pull offs.
He got tired at the end. That stretch at the end is not easy. You play too? I play bass.
