"Tighten Up" is a song by the English band Electronic. Written, performed and produced by its two members Bernard Sumner and Johnny Marr, it appeared as the third track on their debut album Electronic in May 1991 and was also a promotional single in the United States five weeks later. Donald Johnson from A Certain Ratio contributed drums to the song. The single edit is one minute shorter than the album version; the opening bars and the instrumental section are both edited. The song also fades out on a loop whereas the original has a hard ending.
