I need the titles for 3 songs.

1. There's a man I know, who's got a heart so full of joy, it can make you fly. There's a man I know, who's got a soul so full of pain, it can make you cry.

2. The joke's on me. I thought that I knew it all, but one look at you and I find myself falling.

3. Tropical paradise, but the beauty escapes me. Everything should be so right for falling in love.
