One of the Aggie songs

Sons of California

We're sons of California, 
A loyal company,
All shout for California
While we strive for victory.

All sing the joyful chorus
As her banner we unfold,
Then hurrah for California
And for the Blue and Gold.

In addition to Hail to California, this is another song of Brick Morse.

The Cal Band certainly still plays this song! It is still strong as the second song in Cal's pregame show at football games! At the end of the first verse is typically also a spell out of C A L I F O R N I A.
