Paul Rogers told Halesowen News about this song: "Voodoo was a song I had already when I came into the studio. We really just jammed on it, I picked up an acoustic guitar and played it, then Roger (Taylor) came in on the drums, Brian (May) then joined in, and we played through it. We recorded the second or third take. It ended up being quite a sparse song with not much instrumentation on it, and dare I say it, very bluesy, very loose."
George Harrison's 1971 song "Bangla Desh" was the first major charity single. It was part of a concert held to bring relief to the people of Bangladesh, who were fighting for independence and suffering from a famine.
