Sir Paul McCartney releases 'McCartney III' on Dec. 18

Sir Paul McCartney is still rocking it.

While most people spend their time on lockdown binging on TV series and movies, 78-year old Sir Paul McCartney made use of this time to work on a new album – where he wrote all of the songs and played all of the musical instuments.

McCartney III was made completely while on "rockdown" as he would call it in interviews. This now ends the McCartney trilogy that started with his solo albums McCartney in 1970, and McCartney II in 1980.

Talking about McCartney III, Sir Paul revealed, “I was living lockdown life on my farm with my family and I would go to my studio every day. I had to do a little bit of work on some film music and that turned into the opening track and then when it was done I thought what will I do next?"

The musician, best known as one of the former members of legendary musical act The Beatles, went back to his former unfinished work for the album's material. "I had some stuff I’d worked on over the years but sometimes time would run out and it would be left half-finished," Sir Paul continued.

"So, I started thinking about what I had.  Each day I’d start recording with the instrument I wrote the song on and then gradually layer it all up, it was a lot of fun.  It was about making music for yourself rather than making music that has to do a job.  So, I just did stuff I fancied doing. I had no idea this would end up as an album,” he said.

Prior to the official announcement of the album, McCartney’s team did some "teasing" via Spotify and Twitter.
