Hm After 20BST-5 your time, at-least according to this website, is about midnight my time. :/ I guess I might be able to do close to midnight my time, maybe about 8am or later, thatll be evening for you?
I'm a bit busy Friday all day, Satuday will be too late for you probably unless I stay up to 20:00. Sunday might work since I plan on waking up early.
