sub select madness

This one is giving me a headache...

I have a list of works of art that is returned when I search on the
artists name.

I need a sub select that gets the list of expos that each work of art
has been shown at.

Can I have a sub select that shows

year, expo title, organiser, galerie
year, expo title, organiser, galerie
year, expo title, organiser, galerie
repeats as necessary

for each work using just SQL? Or do I have to call a function to get
this to work?

Hope I have been clear

Cheers

Tony Grant
