third Beatles LP in the United States, since Vee-Jay Records had released Introducing... The Beatles in January 1964. Vee-Jay had been able to issue the latter LP – which comprised most of the Beatles' EMI debut, Please Please Me – due to Capitol's initial lack of interest in marketing the Beatles' music. Second Album was a collection of material from various UK releases and recording sessions dating back to March 1963. Included were the five remaining tracks, all cover versions, from With the Beatles: "Roll Over Beethoven", "You Really Got a Hold on Me", "Devil in Her Heart", "Money (That's What I Want)" and "Please Mr. Postman". Added to these were "Thank You Girl", the B-side to the single "From Me to You"; "She Loves You" and its B-side, "I'll Get You"; "You Can't Do That" (the B-side of "Can't Buy Me Love"), from the upcoming A Hard Day's Night UK soundtrack; and two new songs, "Long Tall Sally" and "I Call Your Name". The latter tracks would be released in June 1964 in the UK on the Long Tall Sally EP. Mixes Capitol's engineers, headed by record executive Dave Dexter, Jr., added considerable echo and reverb to the songs in order to give the album the atmosphere of a live performance. The inclusion of "Thank You Girl" marked the only stereo version of the song released on any album in the US or UK for over 40 years, until another stereo version was released on the 2009 remastered edition of the Past Masters compilation. The same stereo mix of "Thank You Girl" on The Beatles' Second Album was included on The Beatles Beat, released in West Germany and the Netherlands, as well as the original 2004 CD issue of The Beatles Second Album as included in The Capitol Albums, Volume 1 box set. The Capitol album mix of "Thank You Girl" is also unique in that it contains three additional harmonica riffs by John Lennon – two during the bridge and one at the end. For its US album debut, Capitol took this stereo version and transferred it into a two-to-one stereo-to-mono mixdown for the mono LP release, thus creating an alternative mono mix of the song. The stereo version of "Money" also underwent the same two-to-one stereo-to-mono mixdown, thereby creating another alternative mono mix. For the mono version of "I Call Your Name", the cowbell comes in at
