Transact SQL :: First Values In Multiple Columns Selection

I'm trying to run something like this:

Select ID, FIRST(forename), FIRST(surname) from table1
GROUP BY ID;

I know First doesn't work in TSQL, I used to use it in Access and now need to run something like that in TSQL. Simply getting unique ID with first forename and surname, cause there are some dupes in a table.

There are records like:

ID      forename     surname
--------------------------------
1    John    Kormack
1   James  Dope
2   Erin    Dupes
3   Will  Hugh
3    Walter Heisenberg

So I want to pull out:

1 John Kormack
2 Erin Dupes
3 Will Hugh

How can I run it in TSQL?
