I'm thinking it might be this. A new song on the Greatest Hits to tide us over until the new album.It could be a new song that’s a one off single for a greatest hits album and not a new album.
Good news. “Life” is a wonderful song and Conrad and Delta sing together beautifully. I was at Conrad’s show in Melbourne last month and Delta came out and they sang “Landslide” together - such a beautiful moment.according to this on july 7th conrad and delta will release a song called life its a song from his new album. so i think she will be performing a song with him on the voice sunday night
