"As Time Goes By"

You may be looking for the comic story.

"As Time Goes By" was an Earth song.

The Seventh Doctor crooned it on Terra Alpha. Earl Sigma also played the song on the harmonica. (TV: The Happiness Patrol)

In 1941, a pianist played it in a café in Casablanca in 1941 to the displeasure of the café owner. (COMIC: As Time Goes By)

Some of its lyrics were:

It's still the same old story

A fight for love and glory

A case of do or die

As time goes by

and

A kiss is just a kiss...
