"American Libraries" wrote of Tunzi's first edition of "Elvis Sessions," "The genuine musical genius of Elvis Presley, has, to a large degree, been obscured by the tragic excesses of his last years and the seemingly inexhaustible supply of tabloid drivel about him. "Elvis Sessions: The Recorded Music of Elvis Aron Presley 1953-1977" eschews such nonsense and sticks with the facts about Elvis's recording career, resulting in a solid bit of American pop music history." One of the unreleased recordings by Presley that Tunzi documented in "Elvis Sessions II: The Recorded Music of Elvis Aron Presley 1953-1977" was an acetate recording he personally owned of "A Little Less Conversation" originally thought to have been made in June 1968 during the production of the "Singer Presents...ELVIS" NBC television special. However, it has since been determined that this acetate recording was actually an alternate take made in March, 1968 during the soundtrack recording sessions for the 1968 Metro-Goldwyn-Mayer motion picture, "Live a Little, Love a Little". A backing track of "A Little Less Conversation" from the "Live a Little, Love a Little" recording sessions was submitted for the 1968 "Singer Presents Elvis" television special but ultimately was not used, which lead to some of the confusion regarding the date of the acetate recording. In the mid-nineties, Tunzi sold to Bertelsmann Music Group (now owned by Sony Music) the unreleased recording that first appeared on the 1998 double album and was later used in the 2001 Warner Brothers motion picture Ocean's Eleven (2001 film) and ultimately remixed by DJ Junkie XL. This remix became a worldwide number one hit, part of a marketing campaign for Nike, Inc.'s "Secret Tournament" Scorpion KO during the 2002 World Cup and a bonus track on the chart-topping compilation ELV1S 30 #1 Hits. Opdyke also wrote of Tunzi's first two volumes, "Tunzi's 1993 "sessions" book first came out through mail order only. Recently it appeared in a revised edition (412 pages) that quickly became even more useful than the first. There were many great photos along with endless appendices covering gold and platinum records, concert lists, and even a limited bootleg section." In November, 2016 Jeremy Roberts wrote an article detailing Elvis' connection to guitarist and entertainer Glen Campbell and the fact that Campbell has been erroneously cited for several years as having played guitar on the recording sessions that produced the title song, "Viva Las Vegas (song)" of Presley's 1964 film.
