Conditional Union!

Hi all,
I have a query that if it returns data i want to perform a union on it.
IE: Select * FROM myTable WHERE myColumn = 'a' ORDER BY NEWID()
If (? Above query returns rows)
UNION
SELECT * FROM myTable 2 WHERE myColumn = 'b' ORDER BY NEWID
Is this kind of thing possible'
A basic example would be great!!
Cheers,

IF EXISTS (Select * FROM myTable WHERE myColumn = 'a')
Select NEWID(), <explicitly specify columns> FROM myTable WHERE
myColumn = 'a'
UNION ALL -- Use a UNION ALL in most cases
SELECT NEWID(), <explicitly specify columns> FROM myTable 2 WHERE
myColumn = 'b'
ORDER BY 1
