I played this Black and White, somewhat washed out, youtube video of
“Lawrence Welk live at the Aragon Ballroom of Pacific Ocean Park in 1960”
for my mother the other day and was surprised to find that there was at least two 1960 Dodge Dart commercials in it involving the Lennon Sisters.

in one of the Dodge commercials they stated that the 1960 Dodge Dart achieved 24.9 MPG in the Mobil Oil Marathon of the previous year.

This video really needs the computer aided colorization technology of Turner Classic Movies
