Cha Cha! Billy May is a studio album released by Billy May in 1960 on Capitol LP record T1329 (monophonic) and ST1329 (stereophonic). The album features instrumental Latin renderings of big band standards and theme songs of many top musical outfits. Many of the arrangements are done tonge-in-cheek, even Capitol's own publicity described "Twelfth Street Rag-Cha-Cha" as "unforgivable".
