Over 100 major musicians -- including Paul McCartney, Bruce Springsteen, U2, Elton John and Don Henley -- have joined a worldwide call for the release of the two jailed members of the Russian feminist punk group Pussy Riot. The two women will make an appeal for parole this week.

In an open letter coordinated by Amnesty International, the artists pledge their support and state that the impact of Pussy Riot’s “shockingly unjust trial and imprisonment has spread far and wide, especially among your fellow artists, musicians and citizens around the world.”

The letter continues: “While understanding the sensitivities of protesting in a place of worship, we ask that the Russian authorities review these harsh sentences, so that you may return to your children, your families and your lives."

Yoko Ono, who signed the letter, says:  “I thank Pussy Riot for standing firmly in their belief for Freedom of Expression, and making all women of the world proud to be women.”

Others signees include Bryan Adams, Joan Baez, Jeff Beck, Jackson Browne, surviving members of The Clash, Peter Gabriel, Billy Joel, Mark Knopfler, Graham Nash, Aerosmith's Joe Perry, Ozzy Osbourne, Sting, Pete Townshend, Eddie Vedder and three former members of R.E.M.
