Question My apologies for posting the Josh Groban songs under cultural references a few days ago without a source I wasn t even thinking about that to be honest I just thought somebody else might be interested which Groban songs were featured Sure got deleted quick but anyway I found a blog that confirms what I posted here but I m not sure if that s a reliable source To me it seems as reliable as somebody s online episode review but I thought I d ask here before adding anything to the article It s not disputable that it was Groban s music in the episode right Even though he wasn t a guest voice
