 All four of the band members sent him their approval by telegram.According to author Peter Doggett, McCartney had felt the need to accommodate his bandmates when accepting Spector's version of "Let It Be"; but, following his announcement of the Beatles' break-up in a press release accompanying the release of his solo album, "McCartney", on 9 April, he repeatedly listened again to "The Long and Winding Road" and came to resent Spector's additions.On 14 April, with manufacturing underway for "Let It Be", he sent a terse letter to Klein, demanding that the harp be removed from the song and that the other added instrumentation and voices be reduced.
