BIRD ON WING
Even as Ronald Reagan is out building a base for 1976, his conservative homilies are not scoring too well at home. His daughter Patti, 21, an aspiring singer and sometime waitress, was spotted arm-in-arm in residential Laurel Canyon with mustachioed banjoist Bernie Leadon and thence in Europe on tour with his country-rock group, the Eagles. Leadon and his four cohorts aren't exactly Boy Scouts (leader Glenn Frey once confessed, "I'm in the music business for the sex and narcotics"). Their outlook is also clearly antiestablishment—in concert, they sometimes facetiously dedicate their hit title Already Gone to the Grand Old Party of Patti's father.
