O/T - Dolly/Kenny "Real Love"

I recall hearing this version back when:

But, on numerous compilations released since 1985 from
both artists that contain this song, this version is
used:

The difference that I hear is minor - in the second verse
around 2:35, Kenny sings "You know I love you too"
differently. On the album version, "too" is stretched
into two notes versus one on the 45.

Is there anything else different between these versions
that I am not hearing? And, of course, I must ask why
two versions were released.

One thing I noticed was the timing of the second chorus. The "You know I love you too" part.

On the first link it shows up at 2:35 as mentioned by Scanner.

On the second link it is nearer to 2:25. So, I guess there's some changes in the early parts of the song that are different too.

There's some conflating of issues that may not be
apparent at first glance.

The first link has 10 seconds before the needle is
dropped so the vocal phrase will appear 10 seconds later.

Nobody really pulled the wrong tape at RCA for this
difference. On the album, one version was cut originally
and then when the single was made they pasted what sounds
like the vocals from the first pass of the chorus. Keep
in mind this was done in 1985 and not some pulling for a
greatest hits decades later.

There's some parallels here with the discussions we had
about Dan Seals' "Bop" and even the recent "Superfreak"
thread where there was a successful dubbing of one line.
When Earth, Wind, and Fire did their rhythm guitar, it
was dubbed so that there wouldn't be alternate phrasing
and little deviations on a part that would be repeated
and almost used to keep time.

When they brought Kenny in he probably did several vocals
for each line. Artists don't really sung the song in
complete takes. Considering this a duet more has to be
"pieced" together. If you watch the video of the making
of "We are the World", that's pretty much how much vocals
get recorded. It looks segmented because there are so
many different singers but many songs especially pop ones
go down in that fashion.

When Kenny and Dolly sung in unison on this and "Islands
in the stream", I thought Kenny always got turned down a
bit but Dolly would stand out against anyone when singing
a phrase together.
