Polymer Records: Tap label from "Shark Sandwich" in 1980 to the 1984 "This is Spinal Tap" soundtrack. The band’s previous label, Megaphone, had abandoned the band after a squabble over royalties. Tap had its problems with the now-defunct Polymer and parent Polygram, as well. A recent legal tangle between MCA and Polygram over the Motown catalog was actually a "smoke screen" to hide a more vicious tug-of-war for rights to Tap songs, according to Derek.
