Uh, I saw it on tv around when I was 5-9 so, ’68-’72. I was at my grandparents house and their tv was black and white so I don’t know what the film was in. There was a little girl and boy who went by a little canoe to a little play camp on an island and ate canned spaghetti. They played house and on their way back, the canoe flipped and the boy drowned. I’m sorry but that’s all I remember
Maybe…”Hand in Hand”(1961)
Although filmed in England in the summer of 1960 under the title “The Star and The Cross”, it was for some reason kept on the shelf and not released in the UK until April 7th, 1963, by which time the title had been changed to “Hand in Hand” and it went out on release on the ABC circuit as the supporting film to the Tony Hancock comedy “The Punch and Judy Man”.
