Identification: Indoor House Plant...unknown

Hi everyone!
Was hoping someone could help me identify this huge tall indoor houseplant that we've had for years and forgotten it's name!

Hope the pictures help but let me know if you need details (bear in mind that I'm a plant-newbie though ;)

I believe that's Dracaena fragrans.

 

You are absolutely right, Eric la Fountaine, thank you!
