I can't find this choral song?

There is a song I sang with my choir some time back, and I can't find any video of it, any sheet music, nothing. Could You help me find it?

The song is only called "Alleluia" with nothing added on to it.I can only remember the last bit where the sopranos had to hit an A5 at the end.I think the BPM is around 150 to 170, aka, it's a little quick (especially at the end since it's the only part I remember)There was a crazy piano part at the end that went up the scale."Sing Alleluia" was repeated at least four times during the end, and finally finishing with an "Ah!" with the sopranos' high notePlease help!
