Two-gluon radiative corrections to the b{yields}cl{nu}{sub l} decay width have been computed analytically as an expansion in terms of (m{sub c}/m{sub b})<<1 in the kinematical limit of zero lepton invariant mass. The obtained results match smoothly with a previously known expansion around (1-(m{sub c}/m{sub b}))<<1. Together they describe the process b{yields}cl{nu}{sub l} for all mass ratios (m{sub c}/m{sub b})
