John has recorded so many hit duets he even released an album entitled "Duets," which peaked at No. 25 on the Billboard 200 in 1993. Following his classic pairing with Dee, Elton graced the Hot 100 with the likes of Aretha Franklin, George Michael (their "Don't Let the Sun Go Down on Me" hit No. 1 in 1992), LeAnn Rimes and RuPaul(!), whose dance remake of this song, from "Duets," dented the chart (No. 92) in 1994. John's current album? The collaborative "The Union," with Leon Russell, which stands as John's top-charting set (No. 3) on the Billboard 200 since 1976.
