Joining Tags Tables and Related Rows

I have a tags table, a cross reference table, and then a primary table.
Selecting from the primary and joining the tags is no problem

SELECT primary_tbl.*, GROUP_CONCAT(DISTINCT tags_tbl.text) AS tags
FROM primary_tbl
LEFT JOIN xref_tbl ON xref_tbl.prime_id =
LEFT JOIN tags_tbl ON = xref_tbl.tag_id

But what I'm now trying to do is a SELECT a row from the primary table plus any other row that matches the tag text.

So if rowA had a tag of 'foobar' I want all other rows with the same tag.

Now obviously I could just separate the statements in my code, but I want to shoot for a single SQL-transaction.

Any advise?
