Let it Be was the last album the Beatles released as a group in Spring 1970. As they did with other albums at or near their 50th anniversary a newly remastered version is released. Giles Martin, son of legendary producer George Martin, did the remastering. This re-release is available in a variety of sizes and formats. I resisted the temptation of buying the super deluxe version with 5 CDs at $118. I compromised and bought the 2 CD version for about $20. The second CD includes outtakes and alternative versions.
I guess the bottom line, literally, is that there are big bucks for everyone including the record company, Paul McCartney, Ringo Starr, and the estates of John Lennon and George Harrison.
