On this day in music history: July 3, 1971 - “Mr. Big Stuff” by Jean Knight hits #1 on the Billboard R&B singles chart for 5 weeks, also peaking at #2 on the Hot 100 on August 14, 1971. Written by Joe Broussard, Ralph Williams, and Carroll Washington, it is the biggest hit for the New Orleans, LA born soul singer. The track is recorded at Malaco Studios in Jackson, MS on May 17, 1970 with producer Wardell Quezergue. “Mr. Big Stuff is recorded on the same day and with the same musicians as King Floyd’s chart topping "Groove Me”. A few months after the session, the master will be sold to Stax Records in Memphis, TN, who will release it almost a year after it was recorded. An immediate smash on the R&B singles chart, it will quickly cross over to the pop charts, crashing into the top five by late Summer. The song will have a long life after Knight’s original version falls from the charts. In 1987, rapper Heavy D. will use the hook for his debut single “Mr. Big Stuff”. Singer Martha Wash will record a cover version of the song for the soundtrack of “D2: The Mighty Ducks” in 1994. “Mr. Big Stuff” is certified 2x Platinum in the US by the RIAA.
