CHICAGO — A man has found a way to demonstrate his trumpet skills, gun prowess and Chicago sports fandom simultaneously on YouTube.

A YouTube user going by the name Charlie Cook has been posting videos of himself playing beloved Chicago sports songs (and your child's favorite "Frozen" jam) on the trumpet ... using a gun as percussion.

Using the hashtags #charliesgungram and #gungram, Cook apparently posts videos by request, including a rendition of "Chelsea Dagger" that was dedicated to his niece for her birthday. It's unclear if they are live rounds or blanks.

On his YouTube channel, Cook writes, "This is Charlie Cook's Personal Shooting Instruction YouTube page. We cover firearms safety, responsible use of firearms and 'good clean fun' with firearms. Safety is paramount!"

According to his apparent Twitter page, Cook is a band teacher and firearms instructor from Massachusetts.

He did not immediately respond to emails for comment Wednesday afternoon.

Other songs memorialized by Cook: "Go Cubs Go," "Happy Birthday," "The Star-Spangled Banner," and "Do You Want to Build a Snowman?" from Disney's Frozen.
