I found this link for 10.7 - http://appldnld.apple.com/iTunes10/041-7195.20120912.d3uzQ/iTunes10.7.dmg
The burning question is how do you uninstall 11, while keeping your library information intact? You can't install 10.7 untill you uninstall 11
Your library will remain intact but it is a good idea to backup before doing this kind of thing.
What you will have to do is rescue your old iTunes library from your Previous Libraries folder and rename it iTunes Library.itl because a newer version of iTunes irreversibly updates your library file.
In this I am presuming nothing radical has changed in how itunes works with library files. As I said, I still run iTunes 7.5 (yes, 7.5, not 10.7)
