[thelist] SQL Issues with NULL Values in Column

I have three tables in my MySQL database:
boots_artists
boots_labels
boots_bootlegs
Using PHP, I want to view a detail of a record in boots_bootlegs, which
has columns for 'artistID' and 'labelID.' I want to pull values from
'boots_artists.artistName' and 'boots_labels.labelName' based on the
appropriate IDs in the boots_bootlegs table. The problem seems to be
that 'labelName' can be NULL, which returns no records when I run this
query.
SELECT
boots_artists.artistName, boots_labels.labelName,
boots_bootlegs.artistID, boots_bootlegs.labelID
FROM
boots_artists, boots_labels, boots_bootlegs
WHERE
boots_bootlegs.bootlegID = '1'
AND
boots_artists.artistID = boots_bootlegs.artistID
AND
boots_labels.labelID=boots_bootlegs.labelID
I'm confused about what to do here. I want to get results, even if the
'labelID' has a NULL value, but obviously I'm not going to because there
is not match.
