Original: Shotton regularly visited Lennon's house (Kenwood) on weekends to keep Lennon company, leaving his wife and young son at home, or to escort Cynthia Lennon for a night out when her husband was busy with band matters or songwriting.
Simplified: Lennon counted on Shotton to be a real friend, who was not only around because Lennon was famous or rich. Shotton and Lennon's wife Cynthia got along well, and Shotton sometimes took Cynthia out for the evening, when Lennon needed to work on music.
