The amalgam of Lp and q consists of those functions for which the sequence of Lp-norms over the intervals [n,n+1) is in q. These spaces (Lp,q) have been studied in several recent papers. Here we replace the intervals [n,n+1) by a cover α={In;nZ} of the real line consisting of disjoint half-open intervals In each of the form [a,b), and investigate which properties of (Lp,q) carry over to these irregular amalgams (Lp,q)α. In particular, we study how (Lp,q)α varies as p, q, and α vary and determine conditions under which translation is continuous.
