I have a client that wants customers to be able to purchase CD's and Sheet music seperately, but when a CD is purchased the customer get a free copy of 1 set of sheet music. Not just any sheet music but shee music of the same name.

Example
Amazing Grace CD
Amazing Grace Sheet - Alto Sax
Amazing Grace Sheet - Clarinet
Amazing Grace Sheet - Flute
Amazing Grace Sheet - Trombone


each of the sheet music instruments are products that can be bought seperate of the CD but one will be provided free when the CD is purchased. How do I get this set up with the option name/value attritubes?
