LONDON (AP) -- Some of Britain's leading musicians have published a letter calling for Russian officials to release a punk band that has been jailed following a protest in Moscow's main cathedral.

The Who's Pete Townshend, former Pulp frontman Jarvis Cocker, Neil Tennant of the Pet Shop Boys and others call for the release of the three members of Pussy Riot in a letter published Thursday in The Times of London.

The musicians say the band members were involved in legitimate protest and should not be facing up to seven years in jail for their actions.

The letter says "dissent is a right in any democracy."

It was published as Russian President Vladimir Putin visits London for talks with Prime Minister David Cameron and a visit to the Olympic judo competition.

Other musicians who signed the letter include Alex Kapranos of Franz Ferdinand, former Smiths guitarist Johnny Marr, Corinne Bailey Rae, Martha Wainwright.

Reports say that Madonna, who Pussy Riot are fans of, will lend her support to the trio during her Aug. 7 performance in Moscow's Olympic Stadium.
