Guy serenades his buddy with favourite song, and forgets the words

Richard is quite the friend. He plays the guitar and piano, self taught and loves playing to friends and family. This day he was recording his buddies favourite song to send via the internet since the buddy was out of town. Richard said he had been practicing on learning the song, but as we know, when its show time, the memory sometimes fades. All in all it went well and Richards buddy Dave appreciated the video done specially for him.
