Barbra Streisand will be singing at the Oscars this year for the first time since 1977. (And only the second time ever, believe it or not.) The Academy's announcement did not specify what song Streisand would be singing, but whatever it is, it'll contribute to this year's ceremony being an extremely song-heavy endeavor: Musical medleys! Adele! Norah Jones! That's ... a lot of singing, Oscars.
