“The good times never have to end,” Brian Wilson sings on the Beach Boys’ “Isn’t It Time.” The sentiment seems particularly ironic given the events of the last few weeks surrounding the Beach Boys’ big reunion, but the song is actually from a cut from June’s That’s Why God Made The Radio.

Now, in a CBS Radio exclusive premiere, the Boys share a new version of “Isn’t It Time,” which is jam-packed with even more harmonizing goodness. Listen below.

Get your fill of the reunited Beach Boys while you can, as That’s Why God Made The Radio may prove to be their last album together. As previously reported, a formal announcement was made last month regarding the future of the band with its surviving members: Brian Wilson, David Marks and Al Jardine will no longer perform with the group. Instead, The “Beach Boys,” at least in a touring sense of the word, will return to its pre-reunion lineup, led by Mike Love and consisting of member Bruce Johnston. Love’s concerts have billed as the “Beach Boys” since 1998, when he licensed the name for his touring use. Love, Johnston and hired musicians have set out on numerous “Beach Boys” tours through the years, often doing it on the cheap and performing the band’s biggest hits almost exclusively.

Wilson and Jardine have spoken out against Love’s decision, urging fans to sign a petition to keep the reunion lineup intact. In fact, Wilson told us back in July that he’d be interested in touring more with the reunited Beach Boys. He even talked a bit about another album for the Boys, to follow-up That’s Why God Made The Radio. “We’d like to capture the Phil Spector rock’n’roll beat,” Wilson said of the proposed album. “Get that rock’n’roll going, you know?”

The Beach Boys will, however, release two new greatest hits compilations next week (October 8).
