请问电影《混合宿舍》插曲是谁唱的？

这是从搜搜问问上找的（转帖了），希望对你有帮助
这是歌词
jokes on you
make out session
ho ho ho it's christmas
take me as i am
everything i want for hamuka

you are the boss
santa's cheer
another time
am i the only one
waiting for you
git it on
you are me(feel so good)
real girl
we wish you a merry christmas
falling fool
heaven
my hearts still breaks

推测是
peter pan carollers or peter pan singers
