HI, There is no legal requirement to add to LICENCE for Apache licensed software but it's nice to have (as you suggest) so we know where they come from, so we can update, check when the licences changes, review releases etc etc
There may be a requirement to add something to NOTICE if google has a NOTICE file for these files (depending on its contents). This is hard to determine as it not packaged as Apache projects are and in fact they link directly to Apache's licence and don't even have their own LICENCE file (in violation of the Apache licence I believe). In it absence we can only assume nothing is required. There is also this [1], which is sort of at odds with the Apache license, but whatever. Basically what you suggest is fine with what we currently can determine, but is not actually legally required. Thanks, Justin 1. http://www.google.com/fonts/attribution
