As she previously teased, it's "a cute acoustic love thing," which she played with her ukulele on Capital FM recently. Only, the song she played is called "London Lights" and not "Someday Maybe," which was the title of the song she and Harry wrote.
Here are the lyrics of the snippet she sang: "Got me looking at London lights/ Wishing you were here with me / In these London lights/ Saying that you love how I got hazel eyes / and honestly, I won't catch up on sleep tonight / I've been looking at London lights and missing you."
Meghan recently explained what the song she and Harry wrote is about: "you know when you date someone, and then you break up, and then you see them on a date with someone else but they're so happy, so you're like, 'I'm happy for you. Maybe some day in the future if we're back together, that'd be cool. Good luck. I haven't seen that smile in a long time, that's great. Maybe some day when we're old and grey, we could be in love once more.' Oops, there's a line!"
