简介：if you are happy儿歌歌词：
if you are happy and you know it clap your hands，
if you are happy and you know it clap your hands，
if you are happy and you know it never be afraid to show it，
if you are happy and you know itclap your hands，
if you are happy and you know it stomp your feet，
if you are happy and you know it stomp your feet，
if you are happy and you know it never be afraid to show it，
if you are happy and you know it stomp your feet，
If you are happy and you know it, Shout "Hurray!"
