Twice as Much was an English duo composed of David Skinner (born David Ferguson Skinner, 4 July 1946) and Andrew (Colin Campbell) Rose (born 12 March 1947, Edgware, Middlesex) and were harmony singers who also wrote much of their own material. They were signed to Immediate Records.

The pair recorded four singles (Sittin’ on a Fence b/w Baby I Want You; Step Out of Line / Simplified; True Story / You’re So Good For Me; Crystal Ball / Why Can’t They All Go And Leave Me Alone) and two albums, Own Up and That’s All (featuring Vashti Bunyan) between 1966 and 1968 for Immediate. Most of these recordings were pop in the Peter and Gordon/Chad and Jeremy mold, with light orchestral pop/rock arrangements, that sometimes employed a touch of the baroque.

Their only UK Top 40 success was a cover of the Mick Jagger and Keith Richards composition Sittin’ on a Fence (1966). The Stones released it a year later.
