This was a truly inspiring performance ❤❤ John and Olivia were great freinds and from when they were very young. They performed a number of concerts together and recorded several albums together including one where they performed each others songs together. Their voices are so complimentary. My favourite songs they they sang togther was Please Don't Ask Me. And Two Strongs Hearts. John singing Grenada with Anthony Warlow is a good example of him singing "opera"
