I concur that it is 'Somewhere my love', also known as Laura's Theme.
As for voices, I can't read the screen behind him, unfortunately. But I can glean a few things that might help.
First, it's not an OTS -- none of them are lit.
Second, it's a mix of three voices -- all three of those *are* lit.
Third, Voice 1 and 2 are from the same group, (same picture) but not the same voice (Different word blur) Voice 3 is something different.
I'm just guessing here, since I don't have access to my Genos for experimenting ... But I'd start with Seattle Strings, a 2nd strings, and French Horn.
For what it's worth, I'm probably completely wrong.
