There is one popular song of Prabhu Deva & Madhuri Dixit having word "K Sera Sera". K sera sera refers to " Jo bhi ho so Ho". I was not aware that K Sera Sera is actually some pharse and it has some meaning.
I searched internet wherein I found that this is Spanish word and actually as 'Que sera sera ' and means -Whatever Will Be, Will Be. There is one popular song with starting line as Que Sera Sera & were used in "The Man who knews too much" made in 1956.
This is just for information,
