London: Former Beatles star Paul McCartney said he once attempted to write a song about Eric Garner protests.
McCartney, 72, said however his attempts have not gone as planned and he is not giving up on creating a protest anthem, reported Contactmusic.
"I was thinking recently about all these protests in New York and around the country. I thought it would be great to put something down about that, just to add my voice to the thousands of people walking in the streets.
"I'm not giving up on it, but it didn't come easily, whereas some other emotions might come easily to me," said McCartney.
Eric Garner was killed by a police officer in New York on July 17 and since then people are protesting against the government and recently many celebrities have showed their support in the protest.
