Paul McCartney and Jane Asher dated for five years. For about three of those years, the Beatle lived with his girlfriend and her family. He adored their family dynamic. Shacking up with his then-girlfriend was a distinct pleasure that broadened the musician’s horizons. At the beginning of their relationship, McCartney would always check himself into a hotel after visiting with Asher and her family or rush off to catch a flight out of Heathrow for Liverpool. But he hardly stayed over.
