Joe Keery is "shocked and confused" by the sudden success of his song End of Beginning

Speaking on The Graham Norton Show, he said: "It is crazy. I am shocked and confused about the whole thing. Hearing it in a taxi was cool, and I knew it was big when my grandma asked me about it!"

Joe - who played Steve Harrington on Stranger Things - admitted it has finally sunk in that he will no longer be going back to the show.

Asked if the programme ending has sunk in yet, he said: "It definitely did when the last show came out on New Year's Eve. I woke up on New Year's Day and felt, 'Wow, that's the end of an era.' It is so finite and done which is bittersweet."

The Delete Ya singer enjoyed working on new music during breaks in filming from the show.

He said: "There is so much down-time on set, so I wrote and recorded. Being an actor means a lot of waiting so it's good to be proactive and busy.

"It started as a break-up song but landed in a place of deep gratitude for the people in my life."

Joe recently revealed his Stranger Things co-star Winona Ryder was hugely supportive of his music career and has been a big influence on his tastes.

He told ELLE magazine: "She really knows her stuff - loves music and film, maybe more than anyone else in my life. I'll get a random text, like, 'Here's an isolated Marvin Gaye vocal track from the stems that they never used from this song' - The deepest cuts.

She's like an encyclopedia, and she's eager to share. She's been to a million shows. It's cool to have someone who's just really excited by all of this."

Joe has always been a huge fan of Winona and was "intimidated" by the Hollywood star at first, but once he got to know her, he saw how "invested and passionate she is about work."
