Lloyd Webber's musical，School of Rock，in which he plays with 36 talented child musicians，reminds him of his time as an instrumentalist．

　　Hill shared his story on arriving in Beijing．School of Rock is being staged in Beijing from March 22 until April 14 on its debut(首演)China tour．The musical staged its world premiere (初次公演)on Broadway in 2015．

　　The musical is based on the successful 2003 Hollywood comedy，starring Jack Black．The plot follows Dewey Firm，a failed rock star forced to make money as a substitute teacher at a private elementary school，where he turns a class of straight-A students into a rock band．

　　"The role，Dewey，is the biggest kid．I am a big kid in real life，so this part is not a challenge．When I got the role，I did the exact same thing as Dewey who is a loser，"Hill says．"Working with child actors is exciting．"

　　Thousands of kids auditioned(试镜)．Three-and-a-half months later，36 made the cut．Samantha Zhang plays the role of Katie．She has practiced piano for seven years and violin for four but had to learn to play bass(低音)for the musical．"Not many girls play bass．It's so cool，and I feel like a rock star，"says the 13-year-old，who made her musical-theater debut in 2014．It's the first time for the girl，who lives in Sydney with her Chinese parents，to visit China．

　　Webber became interested in the movie．He wrote 12 new songs．Hill says it's difficult to get Black's acting out of his subconscious．However，Webber's songs enable Hill to make the role his own．

　　"School of Rock is about how music reaches and transforms everyone's life，especially children．"Webber said．"When the substitute teacher turned the straight-A student class into a rock band，it changed his life and theirs forever．"
