We carried out a multi-colour time-series photometric study of six stars that were claimed as ''hybrid'' p- and g-mode pulsators in the literature. The βCep/SPB star γ∼Peg was confirmed and revealed excellent asteroseismic potential. HD∼8801 was confirmed as a ''hybrid'' δ∼Sct/γ∼Dor star; additional pulsation frequencies were detected. 53∼Psc likely is an SPB star and the O-type star HD∼13745 showed small-amplitude slow variability. No light variations were detected for HD∼19374 and, surprisingly, ι∼Her.
