  A selection of recent results on hadronic charm and beauty decays from the
CLEO experiment are presented. We report preliminary evidence for the existence
of final state interactions in B decays and the first observation of the decay
B0 -> D*+D*- with a branching fraction of (6.2^{+4.0}_{-2.9}+/- 1.0)x10^{-4}.
We also present preliminary results on the first observation of the broad,
J^P=1^+, charmed meson resonance with a mass of
2.461^{+0.041}_{-0.034}+/-0.010+/-0.032 GeV and a width of
290^{+101}_{-79}+/-26+/-36 MeV and branching fraction measurements of the B- ->
D_J^0pi- decays. Finally, we report on search for the radial excitation of a
spin 1 charmed meson, the D*'+, and on an improved measurement of the ratio of
(D0 -> K+pi-)/(D0 -> K-pi^+) decay rates.
