Strung Up is a 1975 double album by Sweet released by RCA Records in 1975. The first disc contains seven songs recorded live during a concert at the Rainbow Theatre, London on 21 December 1973. The second one contains ten selection of their songs recorded since 1973, including three songs that have not been released previously on any album, ("Burn On The Flame" and "Miss Demeanour") but only one ("I Wanna Be Committed") is brand new. The album also includes a unique mix of Action that comes to an abrupt end, and does not include the final decaying echo of the shorter single and longer Give Us A Wink album versions.
Strung Up was not originally released in the United States. In Japan it was released by Capitol Records under the title Anthology. In Italy it was released as 2 separate albums - the studio set entitled Strung Up (released 1975) and the live set entitled Live In England (1976).
To date, the album has been re-issued on CD only in the United States in 1997 on Chinebridge Records and in Japan (as Anthology). These releases include the standard album version of Action. In 1999 RCA released a CD entitled Live at the Rainbow 1973 that contains the concert from the original album in its entire length.
