As in the melody only. I don't mean songs that have, for example, 'Yellow Submarine' in their lyrics. I mean songs by artists who aren't The Beatles that sound like the tune of a Beatles song 
I have 2 so far:
Lily Allen - Not fair (Chorus)
Sounds like Yellow Submarine (Chorus)
Adele - Rolling In The Deep (Verse)
Sounds like Lady Madonna (Chorus)
What about yours?
