In this talk we discuss gluon radiation in top production and decay. After
reviewing results for hadron colliders we consider soft gluon radiation at
lepton colliders and present gluon distributions that are potentially sensitive
to production-decay interference effects.Comment: 8 pages including 4 figures, LaTeX; talk presented at the Workshop on
