“Selling I. B. M.” to be sung to the tune of “Singin’ in the Rain,” from the 1937 corporate hymnal Songs of The IBM:

Selling I. B. M., we’re selling I. B. M.,
What a glorious feeling, the world is our friend,
We’re Watson’s great crew, we’re loyal and true;
We’re proud of our job and we never feel blue.
We sell our whole line, we’re there every time,
To chase away gloom with our products so fine,
We’re always in trim, we work with a vim,
We’re selling, just selling, I. B. M.!
