That fact did not keep me from enjoying this collection — probably because it includes both 'pure' doo wop as well as songs that are closer to doo wop-influenced rock 'n' roll: "Runaround Sue" (Dion), "Shout! Shout! (Knock Yourself Out)" (Ernie Maresca), "You" (The Aquatones), "You're The Apple Of My Eye" (The Four Lovers), and "Come A Little Bit Closer" (Jay & The Americans). It really is a blast...or am I supposed to say, "It's swell!"? OK, maybe not.
Now, if you happened to buy this set during a PBS fund raiser, that's OK. There are many routes to good music and the path itself does not affect the songs one little bit: the music can stand on its own.
