"State of Shock" is a 1984 hit single by The Jacksons featuring frontman Michael Jackson and Mick Jagger. It was written by Jackson and guitarist Randy Hansen. "State of Shock" charted at number 3 on the US Billboard Hot 100 and number 14 on the UK Singles Chart. The track was originally sung with Freddie Mercury as a duet with Jackson, and was later slated for the Thriller album; however, due to differing time schedules, Jackson ended up releasing it with his brothers and Jagger. A clip of the song (an instrumental part) was used on the Immortal album in 2011.
