  We briefly review the existing psi(2S) data taken at RHIC, the Tevatron and
the LHC. We systematically compare them with colour-singlet-model predictions
as a function of the center-of-mass energy, of the quarkonium rapidity and of
the quarkonium transverse momentum. The overall agreement is good except for
large transverse momenta. This points at the existence of large NNLO
corrections or points at colour-octet dominance.
