PlayerAddedEarly event - how can I use it?

If I were to code the following:

Allowed = {"XanthicDragon", "InsertNameHere"}
k = false

function KickRandomPlayer()
    local Players = game:GetService("Players").NumPlayers --Is that the variable? I may be wrong
    local random = math.random(1, Players)
    game.Players:GetChildren()[random]:Kick()
end

game:GetService("Players").PlayerAddedEarly:connect(function (Player)
    for _,v in ipairs(Allowed) do
        if Player.Name == v then
            k = true
        end
    end
    if k then
        KickRandomPlayer()
        k = false
    end
end)

Would this event fire and kick a random player if one of the players found in "Allowed" were attempting to join a full server?
