Return of the champions - days of our lives

In the original two choruses, Brian provides Roger with the harmonies in this song.
After the guitar solo, there is harmony there, but does not appear to be Brian who is singing it.
Any ideas who this is?? Sounds like Brian, although he is just playing, and is no where near a mic.

jamie moses and danny miranda also sing along, so its possibly them you heard. if you listen to bootlegs of gaga, like New Jersey 2005 for example, you hear someone singing right out of tune which im sure is jamie moses!

Thanks for the thought.
It was also interesting to see that Spike provides the synthesized vocal part in radio ga ga for the live shows.
Do we know if this was the case for the live shows for the Works and Magic tour??
