Macklemore & Ryan Lewis have thrown their support behind an anti-discrimination campaign by allowing their hit song Same Love to be used as the soundtrack for a new public service announcement (PSA). The hip-hop hitmakers also feature in the advert for Characters Unite, a public service programme which was created to address the "social injustices and cultural divides still prevalent in... society", and they are happy to have their gay rights anthem adopted by organisation officials. A statement from the Grammy-winning musicians reads, "We intended Same Love to help spread a message of love, tolerance and acceptance and we are proud to align ourselves with the Characters Unite movement which shares the same goal. "Through the new Characters Unite PSA, we hope to inspire even more people to take part in such an important cause." Other stars who have taken part in the PSA, titled I Wont Stand For, include actors Matt Bomer, Patrick J. Adams, Gina Torres and Reshma Shetty. Macklemore & Ryan Lewis performed Same Love with Madonna and Mary Lambert at the Grammy Awards last Sunday (26Jan14), when Queen Latifah officiated marriages between 33 gay, straight and interracial couples as part of the stars' set.
