Written and produced by Curtis Mayfield and released on his Curtom label, collaboration "Let's Do It Again" was originally part of the soundtrack to the film of the same name starring Jimmie "Dynamite!" Walker, Bill Cosby and Sidney Poitier (who also directed the film). The song's sexual subject matter was controversial with old school Staples fans who were rooted in the church, but the song remains in the group's canon. Mavis Staples' voice from the song was sampled in 2011 by Star Slinger, but she isn't suing: "Her manager played the remix I did and she actually liked it!" Darren "Star Slinger" Williams said with enthusiasm.
On the 2007 Wu-Tang Clan album 8 Diagrams, group leader and producer RZA decided to go for something a little bit different. “The whole trick is, 'Will you be satisfied with the unexpected?'" he told Rolling Stone. In this case, that meant using the Beatles’ “While My Guitar Gently Weeps” as the basis for a song called "The Heart Gently Weeps." RZA recruited John Frusciante and George Harrison’s son, Dhani, to play guitar on the track. "Dhani is super-professional," he said. “I try to explain that to the hip-hop people, because sometimes we all stuck on this money s---, but if you do music first, money is going to come."
