"Prove your love": it's my fav song on the album, but also one of my fav Chris' songs, along with "Isn't it midnight", "You make loving fun", "Ricky", "Brown eyes", "Wish you were here", "No road is the right road", "Songbird", etc...
This song make me relax and dream. Her voice in so sweet and smooth, so pure that if I close my eyes it seems like she's going to caress my face (ok ok, I know... I'm in love with her, so I must sound a little bit crazy to you
)
