I'm a beginner/intermediate pianist, and I'm really interested in playing some songs done by Paul McCartney on the Piano, they seem really easy, but I can't seem to under the chords to these songs, please it would help me a ton if someone can help me with the chords, I couldn't find any Sheet Music for these due to the fact there originals and bootleg. and Paul McCartney is why I picked up the Piano!

I really would like to play this for a local cabaret
here are the sample songs I want to do, Thank you for reading
