I present a mini-review of the masses and couplings of the bare (unmixed) light scalar mesons : qq, (qq)(qq), (qq)(qq), gg from QCD spectral sum rules (QSSR) and low-energy theorems (LET) which we compare with recent lattice calculations when available. Some unbiased comments on the different scenar
