Who was the most successful Beatle after the breakup?

I don’t think he was actually born as Sir Paul McCartney

Wally McGhee 🐥, how long they lived? Probably sales.

Wally McGhee 🐥, It's in the explanation. McCartney had the most Top 100 singles and the most Top 10 singles.

Successful by what measure?

@Laura - my point being that the qualifier was not in the question which makes the question ambiguous.

Player #25874027, he was not born as Sir Paul, that title was bestowed on him. Careless management of questions, this game had errors.

Not a huge fan, but he is a talented musician.
