Welsh singer CHARLOTTE CHURCH has pleaded with her fellow countryman SIR TOM JONES to stop singing - because he is "too old". The star insists the 67-year-old crooner should quit the music business before his voice fails, and also urges at 81-year-old singing superstar Tony Bennett to "give up" their careers in the industry. She says, "I think of Tony Bennett in the same way as I do Tom Jones - both are lovely men and huge musical icons but their voices are going now, and their vibrato slowing with age. "I think they should go and live a little, spend their money and enjoy their kids and grandkids. It's time to give up."
