Abstract

We give two proofs for a normality result stated by Singh and Singh (Sharing values and normality of meromorphic functions, Complex Var. Theory Appl. 49 (2004), pp. 417-425) for families of meromorphic functions which share three values with their first derivatives, where the three shared values may depend on the function in the family.
