Brewers Droop (a reference to a slang expression for erectile dysfunction brought on by heavy drinking) was a short-lived southern English rock/blues band best known for member Mark Knopfler, who later shot to fame as a member of Dire Straits. They were formed in Buckinghamshire and released two albums and a 7" between 1971 and 1973.
