Already hitting thousands of view since being uploaded on August 9, Mick Konstantin's catchy, 'There's Only One Conor McGregor' is certain to be rolling around fans of the Irishman until fight night against Floyd Mayweather in just over two weeks.
Konstantin, sitting on his couch with only a ukulele for company, gave a floorless rendition of his tune before uploading to YouTube.
The song has already been received well by the Irish contingent due to the lyrics 'You'll do nuthin' and 'He's gonna knock out Floyd Mayweather' inserted in the chorus.
As McGregor supporters prepare to invade Las Vegas for the Mayweather cross-codes encounter, Konstantin's sure-fire hit may well be inflicted on the former pound for pound king at what is expected to be a lively weigh-in on August 25.
Here's the song in full by Mick Konstantin.
