New integrated spectra in the range 5600-10,000 A are presented for 28 LMC and 3 SMC young star clusters. The equivalent widths (W) of prominent features and the continuum distribution are measured. The analysis, supplemented by 8 additional LMC clusters from previous studies, indicates that the red supergiant phase is indeed very time-peaked, occuring from 7 to 12 Myr. In addition to the previous case of NGC 2004, it is found that NGC 1805, NGC 1994, NGC 2002, NGC 2098, and NGC 2100 (as well as NGC 2011 to a lesser extent) are undergoing this phase. The red supergiant phase is clearly denoted by strong TiO bands and Ca II triplet as well as a flat continuum or (in extreme cases) a continuum with positive slope above 6000 A.
