Can anybody help me finding some lyric in this movie please?

I watch this film last night on Hallmark Channel in China.It was about the middle of the film, when they four come back from the ball, the background music rises, it's a song I've never hear before. Just simple,lyric words.I can't remember much of it, just in time to put down some of it's translation on the screen,it reads:BOWLING ...Swiming suit...radio ...fuss...maybe a little different from it.I tried every availble ways to find them but all in vain.If anyone know the original lyric please contact me at [email protected],I would be most grateful!
