Courtney Love really must be p---ed off now. Nirvana bandmembers Krist Novoselic and David Grohl want Kurt Cobain's widow to undergo a psychiatric evaluation to see if she's mentally incompetent. The duo's lawyer cites Love's decision to block the release of "You Know You're Right," a song recorded before Cobain's 1994 suicide, as an indication of her incompetence. "This Nirvana music should be out there for the fans," attorney Kelly Corr said. "She's fighting that... We think a rational person in her position would say, 'Yes, let's get the music out.'"
