Query: Light element abundances in He-rich stars   We present an abundance analysis of light elements in He-rich stars. The
analysis is based on both low and high resolution observations collected at
ESO, La Silla, Chile in the optical region and includes 6 standards and 21
He-rich stars. Light-element abundances display a diverse pattern: they range
from under-solar up to above-solar values.
