I need help answering questions to a case.

Question

The case is: Wagner V. Columbia Pictures Industries, Inc.

I don't know if you can find this online or not.

These are the questions I need help with:

1. How might the result of this case have been different if the court had admitted the Wager’s evidence of the “Love Song” contract?
2. Under what circumstances would the Wagners’ evidence of the “Love Song” contract have been irrelevant and yet they would still have been entitled to share of the profits from the “Charlie’s Angels” movies?
