Although credited to "Lennon–McCartney", the song “Yesterday”
was written solely by Paul McCartney who is performing solo.

More than 2,500 cover versions of the song exist, making it one
of the most recorded songs in history.

The Five Satins recorded “In the Still of the Night” in the basement of Saint 
Bernadette Catholic School in New Haven, Connecticut, February of 1956. It  
was originally released on the small Standard label, but was re-released by
Ember Records after strong local sales. It is the only song to have charted on
the Billboard Hot 100 three separate times, by the same artist with the same
version each time. After initially reaching #24 in 1956, it was released again
in 1960 where it reached #81. Then more than a year later in 1961 it reached
#99. 

"The Flying Saucer", or "The Flying Saucer Parts 1 & 2", is a novelty record 
which hit #3 in 1956. It is considered to be one of the earliest examples of a 
mashup, using clips from 18 different songs, each of which was a top 20 hit 
1955 or 1956. Bill Buchanan plays the radio announcer, stating that the
