Beatles song, with no introduction, about a time of celebration (6,3)
I believe the answer is:
easter day
'time of celebration' is the definition.
The definition and answer can be both related to time as well as being singular nouns.
Maybe there's an association between them I don't understand?
'beatles song with no introduction about a' is the wordplay.
'beatles song' becomes 'yesterday' (I've seen this before).
'with no introduction' means to remove the first letter.
'about' indicates putting letters inside.
'yesterday' with its first letter removed is 'esterday'.
'esterday' going around 'a' is 'EASTER DAY'.
Can you help me to learn more?
(Other definitions for easter day that I've seen before include "part of holiday?" , "Time of Christian festival" , "eggs on this occasion" , "When Christians celebrate the Resurrection" , "Egg-giving time" .)
