Sax on the Beach

Sax on the Beach is the first and only album by Bleeding Gums Murphy, Lisa's jazz hero.  It is extremely rare, KBBL did not have a copy of it,  the only copy in town at The Android's Dungeon, at a cost of $50.  When Comic Book Guy realizes that Murphy is dead, though, he raises the price to $500.  Bart ends up buying it for Lisa, using the money he obtained from his lawsuit.
