By day he's the MP for Perth and North Perthshire, but by night Pete Wishart is the keyboard player for the Westminster parliamentary band MP4.

The SNP politician is joined by former Labour MP Ian Cawsey on bass guitar and vocals, Labour MP Kevin Brennan on guitar and vocals, and the Conservative's Sir Greg Knight MP on drums and percussion.
