Theodore records stuff on a tape recorder. Father was in Vietnam. Children's book from 70s

[Madeline]

Help! Main characters name is Theodore, and he was holding possibly a yellow record on the books cover on the moon. His dad may have been lost in Vietnam. Person also thinks it may have been written in the 70s. Possible that the boy would record stuff on a tape recorder."

Madeline, was this a picture book for little kids, or a chapter book for older kids? Do you know what the general "feel" of the book was -- was it adventurous, or sweet, or scary? Any idea why the boy was recording things, or what kind of things (news, stories, other people)?
