the melancholy of haruhi suzumiya.... help?

i was woundering if anyone knew where i could get the song from the melancholy of haruhi suzumiya episode; live alive the dubbed version:

singer: wendee lee
song: god knows

i tried looking but could only find rips from the actuall anime with background noise and stuff if there isnt a official version of the song... can someone help me find one with the sound of the crowd reduced or somthing... :D

thanks in advance :)
