We meet in the night in the Spanish café, I look in your eyes just don‘t know what to say, It feels like I‘m drowning in salty water,A few hours left ‘til the sun‘s gonna rise, tomorrow will come an it‘s time to realize.our love has finished forever, how I wish to come with you!how I wish we make it through! Just one last dance!before we say goodbye, when we sway and turn round and round and round, it‘s like the first time,Just one more chance, hold me tight and keep me warm.cause the night is getting cold. and I don‘t know where I belong,Just one last dance! ‘‘‘
