‘Glee’ season 4: Gaga, Britney covers to come

Gleeks have to wait another eight days to see “Glee’s” season 4 premiere, but Wednesday fans were treated to a taste of the music that the New Directions will be serenading us with this year. Wednesday evening, the “Glee” Facebook page featured a streaming presentation with five songs from the first two episodes of the season, all introduced by Darren Criss (Blaine) and Kevin McHale (Artie). No peeks at footage of the dance numbers for these songs, but the music was backed by stills from the new season.
