Query: Nonradial Modes in Classical Cepheids   Systematic search for multiperiodicity in the LMC Cepheids (Moskalik,
Kolaczkowski & Mizerski 2004) has led to discovery of low amplitude nonradial
modes in a substantial fraction of overtone pulsators. We present detailed
discussion of this new type of multimode Cepheid pulsators and compare them to
similar nonradial pulsators discovered among RR Lyrae stars. Finally, we show
first detections of secondary nonradial modes in FU/FO double-mode Cepheids.
