Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE actor ( Actor_ID int, Name text, Musical_ID int, Character text, Duration text, age int )
TABLE: CREATE TABLE musical ( Musical_ID int, Name text, Year int, Award text, Category text, Nominee text, Result text )

### Question ###
how many actors have appeared in each musical?, and list from low to high by the y-axis please.

SELECT T2.Name, COUNT(*) FROM actor AS T1 JOIN musical AS T2 ON T1.Musical_ID = T2.Musical_ID GROUP BY T1.Musical_ID ORDER BY COUNT(*)
