William: THE ONE & ONLY WELSH WILL (also our vibin' buddy & he's also a lowkey roadman).
He's going to be something in the future & i'm paying for him to come to MANNY 0161 & I definitely got to go to WALES to see the sheep & gotta BEACH VIBE. We also gotta carpool karaoke with ROS & SARA (ADHD G).
Wish you the best Will, now & for the rest of your life (BOOMER).
P.S.
