To be clear, this tiny baby isn't actually singing or performing Angus Young's finger-ripping guitar solo from 'Thunderstruck'.
No, baby Ryan's father - video editor Matt McMillan - cut together a year's worth of footage of his son gurgling, slapping the couch, vocalising and whatever into a soundboard, from which he then fashioned together a decent cover of AC/DC's 1990 hit, 'Thunderstruck', from the album 'The Razor's Edge'.
Funnily enough, the song itself was actually taken from a childhood toy that Angus and Malcolm Young played with, so the baby connection is there from the very beginning. Not only that, the song was included the payload for a virus that targeted the Iranian nuclear program.
Every day's a school day around here, folks. Here's the video.
