Daryl Hall and John Oates

Hall & Oates are the best-selling duo of all time, surpassing The Everly Brothers in 1984. They have had 14 Top-10 singles and 5 #1's on the American charts.
Hall is the much more visible member of the group, as he handles most of their songwriting and lead vocals. While Oates tends to pursue interests outside of music (like skiing), Hall is often active with other projects: he's released several solo albums, performed on Eric Clapton's Journeyman album, and sang on "We Are The World." Oates has made other musical contributions - he co-wrote the Icehouse hit "Electric Blue" - but it's become a bit of a joke how Hall tends to dominate the spotlight. Saturday Night Live did a bit poking fun of Oates for doing the hand claps on "Private Eyes."
Hall and Oates are from Philadelphia. They met while attending Temple University.
Hall's birth name in Daryl Hohl.
They have some serious credentials in the world of Soul music. Hall sang with the soon-to-be-famous producers Kenny Gamble, Leon Huff and Thom Bell on a single for Kenny Gamble & the Romeos. The duo has inducted both The Temptations and Smokey Robinson into The Rock And Roll Hall Of Fame, and their hit "I Can't Go For That (No Can Do)" was one of the few songs by a white group to hit #1 on the R&B charts.
