Livin' On A Prayer - Bon Jovi (Feat. Alsou)
 

Sorry if someone has already asked it...
Do you know why Livin `On A Prayer version with russian singer Alsou was cancelled ?

I think it was only ever released as a Russian radio single. No idea why it was cancelled. I don't care for the This Left Feels Right version of the song at all but Alsou is easily more listenable than that other woman who's awful singing made the album.

Was it not on the Russian version of the album?

No it wasn't.
Olivia's version appeared on the Russian CD due to Universal Music Russia's decision.
But as far as I remember it appeared on one of the Alsou's albums.

Both versions are awful.

I agree, both versions are bad :)
