The Band Who...Were Men Of Few Words

Talk about Primitive.

I thought Love Me Do was remarkable for only having 19 different words in the whole song.

I Wanna Be Your Man has only 18!

They are

I, me 

you, your 

love, lover

baby 

be 

can 

let 

like 

man 

no 

other 

tell 

that 

understand 

wanna

Other contenders are Magical Mystery Tour with 36 words, Don't Let Me Down with 40 and Little Child with a positively verbose 46. But the outright winner is I Want You (She's So Heavy) which has 13 (6 of which are in the title).

Calm down Shakespeare!
