J.K. was an Eurodance project made up by Italian producers Larry Pignagnoli and Davide Riva. The first singles were sung by Giovanna Bersola AKA Jenny B.. Lipsync was performed in the videos and on stage by a Polish model called Marta Simlat. Pignagnoli and Riva produced Lalene soon after using the same formula.
The first success of J.K. was You Make Me Feel Good in 1993, it went up to number one in Canada and performed well in France, Germany, Italy and other European countries as well. The songs Beat It and You & I (released in 1994) helped to perpetuate the J.K. success story.
My Radio and later singles were sung by Sandra Chambers AKA Sandy (with the exception of Sweet Lady Night and Go On, which were sung by Zeeteah Massiah). Annerley Gordon AKA Ann Lee is credited on some of the singles as the songwriter.
