The party continues deep into the night, even after Harry has already gone to bed. It’s just James and everyone he loves drinking and laughing: there’s Pandora, Lily, Sirius, Remus, Marlene, Dorcas, and him. Effie and Monty visited earlier in the day not wanting to "ruin" the fun of James seeing all of his friends in the same place for the first time in a while.
