Vocal Snippet that opens the Endless Harmony documentary?

[Rocky Raccoon]

At the very beginning of Endless Harmony, there's a snippet of the boys singing some "ooh aahs" and it sounds very pretty but I can't figure out what song it comes from.

Can't Wait Too Long

[Rocky Raccoon]

No, that's not it.

[wavedancer]

  It sure sounds like Can't Wait Too Long To Me.

[Don_Zabu]

It's the harmony vocals underneath the second verse of "California Girls".

[DonnyL]

it's the background vocals to "california girls"

[Rocky Raccoon]

I just listened to California Girls and yes, that's it!  Thanks.

[wavedancer]

    Yep, I was wrong I just dug it out and it's California Girls alright.

[mammy blue]

OK, I know which part you're referring to now, but there's an acapella Can't Wait Too Long section featured in the doc as well, which is what I thought you were referring to.

I haven't watched it in quite a few years, but I was almost positive it was Our Prayer.

Our Prayer is at the end credits.
