Bird lands on musicians guitar while singing! (1 Viewer)

This is an amazing and cute video I wanted to share with you guys and gals of a unexpected little visitor to hear this bluegrass concert. I wonder why this bird landed on his guitar? :-O

Also can you tell what species it could be...maybe it's a young fledgling but I am not certain.

The bird lands on his guitar at about the 1:28 mark in this video. o

Certainly a fledgling, no idea of species, maybe a Sparrow of some kind?
