About Jim Croce
Jim Croce was an American folk and rock singer-songwriter who achieved great success in the early 1970s, with hit songs like ‘Time in a Bottle’ and ‘Bad, Bad Leroy Brown’. Tragically, his life was cut short in a plane crash at the peak of his popularity, but his music continued to chart and inspire new generations of musicians.
