I've seen her many times, Danny Boy.

Let's meet Barbara's mentor and teacher:

New Jersey, USA born Rhoda Scott, who emigrated to live in Paris. Her father was an AME minister and she gravitated to the organ at an early age. Then she went to music school *grin* . She may be called the mentor of the younger Barbara Dennerlein above.

Both ladies use the Hammond pedals for their walking basslines, rather than the Jimmy Smith style of LH walking while foot "plucks" ala Joey D.

The fast footwork usually indicates an organist who studied the Cathedral Organ classical first, then moved on into the world of jazz.

Rhoda, unlike many of us, never turned her back on her classical organ work either, she simply added the jazz genre to her accomplishments.

Here is Rhoda playing the well known Bach Tocatta in D minor:
