Tamer Hosny at OVO Arena Wembley

What it is. Tamer Hosny is an Arabic music star. The Arena's page says this is the first UK arena show promoted by Live Nation with an Arabic and Middle Eastern headliner, and his first London show in eight years.

When and where. OVO Arena Wembley, Saturday 31 October, with doors at 18:00 and support from Nasser. Under-14s in seated areas must be accompanied by an adult.

Not a Wembley Event Day. Nothing is on at Wembley Stadium on the 31st, so the Event Day Permit Scheme stays out of it and no event day restrictions apply.

Halloween. The 31st is Halloween itself. Boxpark's Remember Them Dayz Halloween night is the evening before, from 18:00 to 23:00 on the Friday.

Show times. Doors are at 18:00, and the Arena has not published a show start yet.

Two nights back to back. The Arena does it again on Sunday 1 November, when Synthony also opens its doors at 18:00.

Second of three. Saturday is the middle of three nights in a row with an Arena crowd, between Macklemore on the Friday and Synthony on the Sunday.

For residents. Your street keeps its usual rules on both nights. Saturday's crowd leaves when the show lets out and Sunday's arrives for doors at 18:00, so the gap between them is the night and most of the Sunday.

What else is on. Troubadour is mid-season with High School Musical, which closes on 3 January.

If you are picking someone up. The Arena gives the finish as 23:00, so plan the drive around then.
