I think it's about people pretending to know the band just because they went to school with them, but they weren't there at the key parts of Liam's memory where he was with a few mates doing keys (loads of Bob Hope) in the back of his mate's garage. Luke was cold so the person who lived in the garage house (obviously better off than them) lends Luke a jumper - a posh one - a Jaeger.
