It means you include any big names ie:
Jesus Christ Superstar (John Farnham, Kate Ceberano, Jon Stevens, John Waters & Angry Anderson), Directed by Richard Wherrett, Produced by Harry M. Miller
(I wish I had that on my resume)
Unlike Matt, I don't usually include the position in the actual show's line, instead grouping by position - so I have a section that lists shows I was Lighting Designer, shows I was Sound Designer, shows I was Stage Manager - mainly because I like to fit the entire show on one line, and "Production Stage Manager" or "Lighting and Sound Designer and Operator" takes up a lote of room. It also means I can prune the resume to taylor it to a job rather quickly by trimming down departments.
