In my ongoing project to give my son as much of a 1970s childhood as possible (Osh Kosh engineers overalls, Fisher Price Little People airport, the one with the crank that moves helicopter and baggage carousel, Old School Sesame Street) we recently ran across all of the 1968 animated film, Yellow Submarine, on YouTube. Now, my son knows who the Beatles are because his older cousins received Rock Band for Christmas, and he spent most of Christmas Day listening to them sing in the family room, so that’s totally 2009. But when “Hello Hello” turns up on the iPod and he stands up in his chair and requests “Lucy in the Sky” it does warm the retro cockles of my heart.
