A Dexy's Midnight Mumbler is a person trying to lip sync the words of Dexy's Midnight Runner's classic hit "Come On Eileen"
Nobody knows the words to Come on Eileen, not even Dexy's Midnight Runners, and they wrote the stupid song.

But 1am at a retro disc, lights down, notice how everyone on the dance floor seems to know the words ..... match perfect?

Here's the real lyrics .........

"Come on Eileen, I swear, well he means
Ah come on let's, take off everything
Pretty red dress Eileen (Tell him yes)
Ah come on let's, ah come on Eileen
Pretty red dress Eileen (Tell him yes)
Ah come on let's, ah come on Eileen, please"

And if you turned off the music suddenly, this is what you would hear from the Dexy's Midnight Mumbler .....

"Come on Elieen ....... da da da I mean
come on yeah ..... everything
and that dress .... and that dress
come on yeah ...... oh Eileen .......... (you get the picture)
