20 years ago today, a limo pulled up to the front of this building, the Hospital of the University of Pennsylvania (3400 Spruce Street Philadelphia); David Ruffin, lead singer of the Temptations, was expiring in the backseat. After Ruffin collapsed in a Philly crack house, his driver sped him to the hospital where the singer succumbed to an overdose of cocaine at the age of 50. Reportedly Ruffin had $30,000 in cash on his person at the time of death, 3:55 a.m., June 1, 1991.

Known for his distinctive tenor and black, thick-rimmed glasses, Ruffin sang lead on many of the Temptations most famous hits, including "My Girl." All the songs you've seen your parents dance and sing to. Wiz Khalifa used the cover of Ruffin's 1980 release Gentleman Ruffin as the basis for his Kush and Orange Juice mixtape.
