This, ' coming-of-age record, was a well-timed and even better executed exercise in modern record-making. The brothers had recorded several excellent - sides on a few labels (including ) in the mid-'60s. They were darlings of the set, and even sang backup on a few unreleased sessions in 1965. By 1967, they were at loose ends. Having demoed a slightly demented song that year called the group entered the studio with producer , who was fresh from some critical acclaim after recording . The resulting album and subsequent title track hit were huge successes, especially on FM radio. The rest of the album shows the brothers not just embracing the trends, but also redefining their leanings. [The 2000 CD reissue of on / adds three 1966-1967 non-LP B-sides, as well as the first single version of which is substantially different from the familiar one on the album.] ~ Matthew Greenwald
