Leon HaywoodLeon Haywood, a velvety-voiced R&B singer-songwriter known best for his 1970s single "I Want'a Do Something Freaky to You," died Tuesday, according to multiple news sources, including Rolling Stone and The Associated Press. Haywood was 74.

The death in Los Angeles was verified by Haywood's godson Darnell Price. The cause of death was not announced.

Haywood's hit was sampled on "Nuthin' But a 'G' Thang," Dr. Dre's duet with Snoop Dogg. 50 Cent also sampled "I Want'a Do Something Freaky to You" on his song "Corner Bodega," as did Aaliyah on her single "I Gotcha Back."

Haywood was born Feb. 11, 1942, in Houston, Texas. He started playing piano as a young boy. By the 1960s, he had moved to Los Angeles, ending up as a keyboard player in R&B singer Sam Cooke's band until Cooke's death.

In 1965, Haywood released the R&B single "She's With Her Other Love." In the 1970s, as the funk and disco hit a groove in the U.S., Haywood altered his style. "I Want'a Do Something Freaky to You" reached No. 15 on the pop chart. He followed up with "Strokin' (Pt. II)" in 1976 and "Party" in 1978. Both tunes rose to the top 25 on the R&B chart. Leon also wrote "She's a Bad Mama Jama" a million selling hit for Carl Carlton in 1981.
