How about tickets to a live musical show in your town or city? You could also gift him a DVD set of his favourite musicals, or a subscription to a movie and TV streaming service like Netflix that has a great selection of musical movies. Additionally, you could consider getting him a soundtrack of his favourite musicals or a book about the history of musical theatre. Another idea could be to gift him a personalized VIP tour of a theatre, where he could meet actors, see the backstage, and learn about the behind-the-scenes of putting on a musical.
Or you can get him a star map with the date when he welcomed you in this world.
