From the recording The Goddess

Imagine the majestic Goddess Juno, ‘Queen of the Gods’, benevolent protector of women and of marriage, arising after a long sleep in a really, really good mood. Oh what a sunny morning that would make!
In Roman mythology, every man was believed to have a protective guardian spirit called a ‘Genius’. This ‘Genius’ would bestow success and intellectual powers on its devotees. Accordingly, every woman had their own version of ‘Genius’ called a ‘Juno’. It follows that ‘Genius’ and ‘Juno’ represent the same qualities but are simply masculine and feminine counterparts.
Also, Juno was believed to have the ability to throw thunderbolts; the image of which conveniently explains all the crash-boom-bang heard at the beginning and ending of this joyfully raucous opener.
