Answer:
True.
Step-by-step explanation:
Murry Wilson was the father of the famous Beach Boys, a record producer, and a businessman who managed his sons' music band. He was also known as the domineering type, strict and even abusive to his sons, especially Brian Wilson.
Gradually, the relationship between the father and the sons/ band deteriorated, resulting in them relieving their father of his managerial position. Thus, it is true that Murry Wilson was ousted from his position as their manager in April 1964.
