Question: What song is an alternative mix of the Beatles' 1970 album "Let It Be" released in 2003, which replaced the 39-second "Maggie Mae" with " Let Me Down"?

<P0-S0>  The project was initiated by Paul McCartney, who felt that the original album's producer, Phil Spector, did not capture the group's stripped-down, back-to-their-roots intentions for the album. <P0-S1>  "Naked" consists largely of newly mixed versions of the "Let It Be" tracks while omitting most of Spector's embellishments and the incidental studio chatter featured between most cuts of the original album. <P0-S2> Let It Be... Naked is an alternative mix of the Beatles' 1970 album "Let It Be", released in 2003. <P0-S3>  "Naked" also omits two minor tracks, "Dig It" and "Maggie Mae", replacing them with "Don't Let Me Down", originally featured only as the B-side of the "Get Back" single. <SEP> <P1-S0>  The song is credited to Lennon/McCartney/Harrison/Starkey. <P1-S1>  It is one of the few songs to be credited to all of the Beatles. <P1-S2>  This song and the 39-second "Maggie Mae" appear on the "Let It Be" album, but are not included on the "Let It Be... Naked" album, instead being replaced with "Don't Let Me Down". <P1-S3>  Glyn Johns' May 1969 version of the album, then titled "Get Back", had a 3:59 excerpt of "Dig It", which was later reduced to the much shorter version in the final album. <P1-S4> "Dig It" is a song by the Beatles featured on their album "Let It Be". <SEP> <P2-S0> Let It Be is the compilation album by Laibach. <P2-S1>  It was released in 1988 and is a cover of the Beatles' album "Let It Be" recorded in Laibach style with military rhythms and choirs, though a few tracks deviate from this formula, most notably "Across the Universe". <P2-S2>  The title track is omitted and "Maggie Mae" is replaced by the German folk song "Auf der Lüneburger Heide" in combination with "Was gleicht wohl auf Erden". " <P2-S3> For You Blue" begins with Moondog's "Crescent Moon March", which is subsequently used as a counter-melody. " <P2-S4> One After 909" includes a small piece of "Smoke on the Water", originally written and recorded by the band Deep Purple. <SEP> <P3-S0> Mono Masters is a compilation album by the Beatles, and is an alternate, all-mono version of the album "Past Masters". <P3-S1>  "Mono Masters" was originally a two-CD set included as part of "The Beatles in Mono" box set. <P3-S2>  The premise of this box set was to compile only Beatles material which was released or prepared for release with a dedicated mono mix (the set excludes later material mixed and released only in stereo, and material whose mono version was simply created as an equal mix of the two channels of the stereo version). <P3-S3>  As a result, the track listing for "Mono Masters" differs from "Past Masters" on the second half of disc two, omitting some later songs that never had a mono mix ("Old Brown Shoe", "The Ballad of John and Yoko" and "Let It Be"), and adding several songs released on stereo-only albums that had unreleased mono mixes. <P3-S4>  Tracks 9–12 and 15 were prepared in March 1969 for release as a 7" mono "Yellow Submarine" EP, two months after the release of the similarly titled soundtrack album, but the project was scrapped, although the EP was mastered. <P3-S5>  Subsequently, the tracks were only released in stereo (and in an electronically produced mono mixdown, or "fold-down", of the stereo mix), while the true mono mixes remained unreleased. <P3-S6>  "Get Back" (with B-side "Don't Let Me Down") was the final Beatles single mixed for mono format. <P3-S7>  It was released in the UK in mono, though the US release was in stereo. <P3-S8>  Thus, the songs that were originally released on stereo singles in the UK are omitted on this release.
