The US Supreme Court let stand a ruling that when Cyril Vetter took back his 1962 song "Double Shot (Of My Baby's Love)," he got it back worldwide, not only in the US. US law lets writers reclaim their rights after 35 years, or 56 for songs from before 1978. Four justices sat this one out, so there is no nationwide precedent yet, and the Fifth Circuit's ruling stands in Louisiana, Mississippi and Texas. We asked songwriters whether they know when their oldest songs can come back to them.
