2nd singer to do harmonies/2nd voice

Native-English speaking singer (or other nationality with a convincing native accent) to sing harmonies / 2nd voice / choruses with Indigo Days. We should be playing a gig July 1st and we need  someone to join us either  just for then or more permanently. You need to be able to sing in tune and not get distracted by the main voice! Would suit a female voice - or Paul McCartney! We are from the UK, Spain and Latin  America, in our 30s/40s and our main  influences are 80s 90s indie (the Smiths, Suede, Pulp, the Sundays), Belle and Sebastian, the Beatles, Big  Star and some current Indie (Temples, Dark, Dark, Dark, Real Estate)etc.
