PLEASE HELP!!! when i was little, i watched a show about 2 girls and the theme song was "do you believe in magic". what was the show called? ive looked for it the past 10 years and still cant find it. Please help!

You might be talking about link. It aired in 2001, just after the nineties. Am I right?

From link: "Set in 1965 this comedy/drama follows the adventures of a 12 year old Jewish girl named Hannah who is best friends with Grace, a 12 year old Catholic girl. They both attend the local Catholic school. This show follows their adventures of growing up in the 1960's."
