How about giving him The Who's new album, "WHO" as a Christmas gift? If he already owns that, you could give him a vinyl record or CD of one of their classic albums like "Tommy", "Quadrophenia", or "Who's Next". Another unique gift idea is to get him a vintage poster or t-shirt featuring The Who. Lastly, you could get him tickets to see The Who live in concert if they're currently on tour or will be soon.
Or you can get him a star map with an important date you share.
