Citizens of Boomtown: The Story of the Boomtown Rats (BBC2, 9.20pm)

WITH a string of successful albums, world tours and two number ones (Rat Trap and I Don’t Like Mondays), for a time the Boomtown Rats were the most successful band to come out of Ireland. But as their star waned, lead singer Bob Geldof revolutionised the charity world with the Band Aid single and the subsequent Live Aid concert in 1985, which saved the lives of millions of people.

The band broke up a year later but in 2013 they answered the call from the Isle of Wight Festival to re-form. This documentary follows the highs and lows of the band, as told by the four members of the re-formed group – Bob Geldof, Garry Roberts, Pete Briquette and Simon Crowe, as well as departed guitarist Gerry Cott.
