In Karaoke Revolution Glee, gamers perform some of the most memorable scenes from Season One, alongside their favorite Glee characters. The millions of fans nationwide that have made Glee one of the leading musical franchises of our time can now belt out up to 35 chart-topping hits and tunes from the popular TV series. Karaoke Revolution Glee will also utilize Karaoke Revolution's proprietary voice recognition technology, which accurately recognizes and scores vocal pitch and rhythm, helping gamers reach those hard-hitting notes and perfect their harmonies!
As far as I know, it has the songs from the first half of season 1. Other prices I've seen go from £17.85 onwards. Free delivery too! Doesn't include the mics (but you can use your Singstar ones).
