I'm putting this in the "MOVIES" thread even though it's a 3-part mini-series that ran on BBC last year. Total running time is 2 hrs 15 minutes, so I'd count that as a movie and not a series.

In the trailer you can spot the actors playing Brian Epstein, George Martin, and at the very end, Burt Bacharach.
For comparison's sake, here's Cilla Black singing her second #1 single:
