"The Lovely Linda" Recording

Paul McCartney had been literally "missing in action" for the last few months of 1969. He had shut himself down and didn't venture out to any public events nor did he attend to any matters relating to the Beatles' company "Apple". In the meantime, to keep himself busy he started to write some new songs, go through some old songs and record a solo album.
The equipment used on some of the tunes were done at 7 Cavendish in London at home with a four track Studer tape machine and a microphone plugged directly through the Studer channel. I guess this basically meant that levels and the equalization of the instruments/vocals would be refined in the mixing stage of the songs.
In order to test out the equipment, McCartney decided to record a short tune dedicated to his lovely wife, Linda. "The Lovely Linda" consisted of acoustic guitar and vocal, second acoustic guitar, percussion and bass guitar - all played by Paul via overdubbing. The song ended up opening the album.
Since the recording equipment arrived at Paul's home before Christmas 1969, most reference books have placed the recording itself in mid December 1969.
The song was mixed in stereo at Abbey Road Studios in the control room of Studio 2 on February 21 1970 after having a trail mix at Morgan Studios in London earlier in February and ultimately rejected in favour of Abbey Road. The work at both Morgan Studios and Abbey Road were booked under the name of "Billy Martin" (a baseball player) as McCartney wanted to keep the recordings secret from the media and the public until it was finished.
"The Lovely Linda" is the opening track on the Apple LP/CD "McCartney".
