Three Dog Night - Celebrate

So as to not further hijack the "One" thread...

There are actually at least 3 mixes of "Celebrate", all of which concern the part you referenced. The difference that jumped out at me was in the handclaps. The original single, the reissue single and what was included on "Big Hits Now" early 70s compilation are all slightly different in that part of the song.
