The group hit No. 72 on the Billboard Hot 100 in 1958 with "Who's That Knockin'," and after a stint in the Air Force, he got back to work in 1965 under his own name (as Roy C.), releasing the single "Shotgun Wedding," which hit No. 14 on the R&B chart; he released his debut solo album, That Shotgun Wedding Man in 1966.
He scored more hits through the late 1960s and early 1970s, including "Got To Get Enough (Of Your Sweet Love Stuff)" and "Don't Blame The Man." He released the Sex and Soul album in 1973. He issued two more albums as part of his Mercury Records deal, 1975's Something Nice and 1977's More Sex & More Soul, with an undercurrent of political and social agitation woven throughout his work on songs such as 1971's Vietnam War protest song "Open Letter to the President" and More Sex & More Soul's pointed "Great, Great Grandson of a Slave."
His most lasting legacy, however, came with a song he wrote and produced for a group of Queens high schoolers called the Honey Drippers, whose music he released on his independent Alaga label. Their most notable track was the 1973 funk single "Impeach the President," an agitation against then-president Richard Nixon.
"Some people say that he's guilty (that he's guilty)/ Some people say I don't know (I don't know)/ Some people say, give him a chance (give him a chance)/ Aw, some people say, wait till he’s convicted (till he’s convicted)/ Impeach the president," they sang on the track, which advocated for the impeachment of the President in the midst of the Watergate scandal that ultimately resulted in Nixon's resignation.
The song's biggest impact, though, is in the booming drums cooked up by Hammond on the track, which have reportedly been sampled more than 600 times on hip-hop tracks, including on MC Shan's "The Bridge," Eric B and Rakim's "Eric B. is President" Kris Kross' "Jump," Dr. Dre and Snoop Dogg's "The Chronic (Intro)," LL Cool J's "Around the Way Girl," Tupac Shakur's "I Get Around," The Notorious B.I.G.'s "Unbelievable" and J. Cole's "Wet Dreamz," as well as songs by Nas, Flo Rida, Digable Planets, Janet Jackson, N.W.A, Big Daddy Kane, Aaliyah, Run-DMC and the Jungle Brothers.
