We calculate dynamical and Bose-Einstein inclusive correlations of pion pairs (as functions of the invariant pair mass M [pi][pi]) from the decay of independently produced clusters, whose finite size is explicitly taken into account. We show that recent pp bubble chamber data from FNAL on the correlation functions C 2(M'[pi][pi]) for centrally produced [pi] + [pi] - and [pi] - [pi] - pairs can be understood within this picture. Some implications for Hanbury-Brown-Twiss type analyses are discussed.
