Freddie was interviewed for the radio show Rock Around the World with Chuck Marshall. The file is labeled Nov 1977 although as I cross-checked with a Rock Around the World website it says the show is on 18 Dec 1977 (possibly the actual broadcast date?).
Thank you to the owner Kamenliter for transferring this, Bob for the original share, Mercury Roadrunner for helping me recover this. Edits by me.
