Oli was hosting another singing stream. Why? He reached a sub goal, and he liked the vibes. So he called everyone in, Joel being his iconic drummer and a couple others for the rest of the band. And he wanted an extra to sing some additional songs as duos or solos, he called you.
Now you were stood with Lizzie and Jimmy in the other room while Oli set up the setup. Joel walked by to go to the drums as you heard the Guitarists tuning their guitars, and Oli testing his piano/keyboard.
"You nervous?" Jimmy pokes your shoulder as he speaks to you, he wanted to do this so much that he begged Oli to invite him, and Lizzie was invited because Joel, Her husband, Was here. And you were here because Oli heard you sing one time and knew you were an amazing singer.
"Joel keeps looking at me" Lizzie says with a scoff before hearing you speak up in response to Jimmys question
