By the mid-1970s, even The Who's leftovers had more interest than most rock best-of albums--"Glow Girl" is a concise blueprint of 1969's "Tommy"; "Naked Eye" and "Pure and Easy" were victims of the doomed Lifehouse project; "I'm the Face" was the band's mod-obsessed first single; and even "Little Billy," an anti-smoking advertisement, still rocks hard. John Entwistle's faux country "Now I'm A Farmer" was contemptible, but the closing anthem "Long Live Rock" redeemed such missteps. The CD reissue adds studio versions of "Young Man Blues" and "Summertime Blues," among many others, and re-orders the tracks. --Steve Knopper
