This talk is an attempt to underscore in detail the physics reach of an experimental set-up where neutrinos produced in a beta-beam facility at CERN would be observed in the proposed large magnetized iron calorimeter detector (ICAL) at the India-based Neutrino Observatory (INO). The "magical" CERN-INO beta-beam set-up offers an excellent avenue to use the "Golden" channel ($ν_e \to ν_μ$) oscillation probability for a simultaneous determination of the neutrino mass ordering and $θ_13$ avoiding the impact of the CP phase $δ_CP$ on these measurements. With Lorentz boost $γ=650$ and irrespective of the true value of $δ_CP$, the neutrino mass hierarchy could be determined at $3σ$ C.L. if $\sin^22θ_13 (true) > 5.6 × 10^-4$ and we can expect an unambiguous signal for $θ_13$ at $3σ$ C.L. if $\sin^22θ_13 (true) > 5.1 × 10^-4$ independent of the true neutrino mass hierarchy.
