The only change was that the length of the tunes tended to fall into the potential radio airplay range of four to six minutes. McDuff and his regular group of the period (Leo Johnson and Danny Turner on reeds, underrated guitarist Melvin Sparks, and drummer Ray Appleton) swing their way through five of McDuff's originals and two obscurities with plenty of spirit, if not a great deal of originality.
