Among the Perry Como material reissued most often is his work during the late '40s, when Como ruled the Hit Parade with soporific but sincere balladry bearing the titles "Till the End of Time," "If," and "Prisoner of Love." It's a slightly earlier era than the good-time material he's usually lampooned for, and it qualified him as one of the best post-Crosby crooners in vocal music. The Prism collection Till the End of Time includes 23 songs from that era, a very good cross-section that includes the three titles listed above -- all chart-toppers -- along with a parade of lesser hits along similar lines, including "You Won't Be Satisfied (Until You Break My Heart)," "Far Away Places," and "I'm Always Chasing Rainbows." Also present are a few of Como's lightweight novelties, such as "Hoop-Dee-Doo" (another number one hit) and "Bibbidi-Bobbidi-Boo." Although many of these songs are marking at least their 50th appearance on CD, Till the End of Time is a fair way to acquire many of them in one place.
