I want to know the answer to the following question:
Who was the new lead singer for Van Halen on 5150?
All the background I'm provided with is that "When Wet (1986), mixed hard rock with a pop sensitivity and spent a total of 8 weeks at the top of the Billboard 200 album chart, selling 12 million copies in the US while becoming the first hard rock album to spawn three top 10 singles — two of which reached number one.". Is that enough to answer the question?
Answer: no
