LONDON, Aug 17: Singer Paul McCartney said yesterday he hoped Russia would not punish members of punk band Pussy Riot, on trial for bursting into Moscow’s Christ the Saviour Cathedral in balaclavas and short skirts and taunting the Kremlin from the altar. The ex-Beatle joined other high-profile musicians including Madonna and Pete Townshend of The Who in calling for clemency in a case that has raised international concerns about Russia’s commitment to free speech.
