20 Greatest Hits collects the most memorable songs from Tommy Roe, Gary Puckett, and Dennis Yost & the Classics IV. Puckett's "Woman, Woman," "Young Girl," and "Lady Willpower" are included on the album, along with Yost's "Traces," "Stormy," and "Every Day With You Girl." Tommy Roe's "Sheila," "Crimson and Clover," and "Dizzy" help complete this entertaining re-recordings that the artists did for the King and Gusto labels in the 80's, and are not the original recordings.
