Bootable Drive for El Capitain

So I'm on Yosemite and was waiting to upgrade to El Cap because I do music production and didn't want to mess with my ecosystem. I was going to download and make a bootable drive of El Cap before it switched to Sierra in the App Store. BUT I woke up this morning to do the deed and saw that it's already switched to Sierra!

So my question is - My wife has El Cap in her App Store purchase history - I should be able to download it from there and make the bootable drive from that, right?
