  The talk covers three contributions on (i) the final measurement of branching
ratios and spectral functions of t decays using the full LEP-I data from ALEPH,
(ii) a preliminary measurement of the t hadronic branching ratios from DELPHI
and (iii) a measurement of the strange spectral function in hadronic t decays
from OPAL. These measurements are discussed and the relevant physics topics are
briefly reviewed.
