playing now in F21- 2 songs...female retro song

Trying to find these songs, heard them in around the same time yesterday in the store.

first one is a girl singing, sounds like a song from the 50's almost, like the Concretes/Pipettes/Noisettes type of song...
lyrics go something like "today was the saddest day, because you took your love away.."
then something like "darling won't you give me on more chance"

other one was a guy singing,
lyrics are " you aren't nineteen forever..."

driving me crazy trying to find these! thanks for any help!

the second song you're talking about is by the courteeners. called not nineteen forever.

the first is One More Chance by Candie Payne

Are you sure it's not "you aren't Seventeen forever?", cuz thats a Metro Station song.

Forever 21 doesn't play Metro Station
