In 1997, it came as a quite a surprise when Fantasy reissued Opa's albums Golden Wings (1976) and Magic Time (1977) on a single 74-minute CD – surprising because the fusion trio had only a very small following; its albums were far from big sellers, and the original LP versions were in print for only a few years. If one notices some similarity between the melodic blend of jazz, rock, funk, pop, and Brazilian music heard on this disc and Airto Moreira's CTI dates of the 1970s, it's no coincidence – Moreira produced both Golden Wings and Magic Time and plays percussion on both of them. Opa members Hugh Fattoruso (keyboards, vocals), George Fattoruso (drums, vocals, percussion), and Ringo Thielmann (bass, vocals) often worked with the percussionist and his wife, Flora Purim, in the 1970s, and his influence clearly rubbed off. It's regrettable that Opa were never as commercially successful as either Moreira or Purim, although this CD points to the fact that it wasn't due to a lack of rewarding material.
"Opa Opa" is the debut single released by the Greek-Swede duo Antique in 1999, that reached gold status in Sweden. The original song was written by Giorgos Alkaios, and has also been performed by Notis Sfakianakis. In 2004, an English version was released internationally by Despina Vandi.
