Markus Haider

Markus Haider is an Austrian singer part of The Gang Guys, who dub themselves "the Austrian Rat Pack", a tribute band to the original Rat Pack.^[1] He is known for his performance of Dean Martin's Sway that is commonly but mistakenly thought to be performed by Frank Sinatra.^[2]

Haider's cover of Sway was a part of a tribute show to the Rat Pack performed at Entropolos Theatre, it is believed that the date of the performance is somewhere around 2009.^[2][3] The black-and-white hue of the video was later added to the video by Niki Lappas - the band's editor - giving the performance a more dated look, resulting in confusion as to the date of the performance and the identity of the performer is, with many uploaders mistakenly classifying it as a Frank Sinatra performance,^[4][5] despite there being no known Sinatra performance of the song. The cacophonous audience featured in the video was spliced from a Beatles performance on February 9, 1964.^{[citation needed]}
