Rise up, Rise Up
From Wikipedia:
In his 2003 run for the leadership of the federal New Democratic Party, Jack Layton asked Segato for permission to use "Rise Up" in his campaign. "Over the years," said Segato, "many political parties have either used or wanted to use the song 'Rise Up' for their campaign. Most of the time, they don't ask. They just use it until you say no. Well, Jack asked to use our song and I said, Forget it, we'll write you your own anthem."
Segato, with Richard Underhill and Lynne Fernie, subsequently penned a new campaign song, "Bringing All The Voices Together", for Layton. While distinct in music and lyrics, it was identified as something of a sequel to "Rise Up." "It's a new version of Rise Up, not the lyrics but the spirit," Layton said.[5]
