In 1961, Kovacs recorded a record album of poetry in the character of Percy Dovetonsils named "Percy Dovetonsils Thpeakth", but was unable to release it due to contractual obligations with other record companies. After he was given the masters, Kovacs donated them to a Los Angeles area hospital. Adams was able to re-acquire the tapes in 1967, and they remained part of her private collection until her death in 2008. The tapes were labeled as movie material and were thought to be such until further examination proved they were Kovacs as Percy reading his poems with no music background. The album was finally released in 2012.
