Who should be dealt cards in the next hand?

[Beck]

I was playing a tourney last night, where a somewhat tricky situation arose.

The setup:
30 player tourney, at 3 ten-seat tables. Down to 21 players, so 7 at each, and the tables will be consolidated when down to 20 players.

At my table, it was as follows:

Seat 1: Empty
2: Empty
3: SB
4: BB
5, 6 & 7: Players
8: Me
9: Button
10: Empty

The SB gets eliminated, and so does another player at another table, so down to 19 players, and one table breaks up. 3 New players arrive at my table, occupying seat 1, 2 & 10. So seat 3 is still empty.

So my question is, where is the button now, and who should be dealt in?
