"Heidrun" is also the name of a Vikingarock band from Värmland, Sweden who originally formed in 2009 as a cover band. Since then their popularity has grown, and they released their first full-length studio album with original music, "Framåt Gå," in August 2012.
Geit sú er Heiðrún heitir stendr uppi á Valhöll ok bítr barr af limum trés þess er mjök er nafnfrægt, er Léraðr heitir, en ór spenum hennar rennr mjöðr sá er hon fyllir skapker hvern dag. Þat er svá mikit at allir einherjar verða fulldruknir af. - 
A goat called Heiðrún stands up [on its hind-legs] in Valhalla biting the buds off the branches of that very famous tree which is called Lærað. From her teats runs the mead with which every day she fills a cauldron, which is so big that all the Einherjar can drink their fill from it. - Young's translation
Since Snorri quotes other strophes of Grímnismál it seems reasonable to assume that he knew this strophe too and used it as his source for his description of Heiðrún.
Heiðrún's name is sometimes anglicized Heidrun, Heidhrun, Heithrun, Heidrún, Heithrún or Heidhrún.
