Dandy in the Underworld is the twelfth and final studio album and a UK-only release by British rock band T. Rex. It was released on 11 March 1977 and reached a chart peak in the UK of No. 26. It was the band's highest-charting album since 1974's Zinc Alloy and the Hidden Riders of Tomorrow. After three commercially weak albums, Dandy in the Underworld was regarded by many T. Rex fans as a comeback for the band. However, it would prove to be the band's final album, as Marc Bolan died in a car crash in September 1977. The album was praised for the strength of the songwriting and Bolan's vocal performances.
The title track was released as a single but failed to chart. "I Love to Boogie" and "The Soul of My Suit" did achieve chart placings in the UK.
