"I hope that in the future we'll have The Stones and The Beatles, Bob Dylan. Who knows?" she added.

Executive producer Pippa Harris pointed out how she and other workers from the series enjoy with these tunes as they look over the scripts.

"Heidi [Thomas, the show's writer] is obsessed with the music, quite rightly," Harris said. "She will write into her scripts particular tracks so that we can play them while we are listening to the first drafts of the script, which is perfect."

The producer then mentioned how the music creates an impact on viewers as they witness something quite different from before.

"It intensifies the scenes which are anyway moving and I think that's one of the things that people love about the show," Harris said. "The music is one of the things that really helps viewers get into a new world each week."

Call the Midwife Season 4 is expected to air in the United States on Sunday, March 29 at 8 p.m. ET on PBS.
