Social engagement for 50 +

My mum (50+) has just moved to the Geelong region and looking to meet new people/develop friendships. She is a young women at heart and so she enjoys live music and going out and about on the town. She is super fun to be around and enjoys a social beer so ultimately a social club at a bar or pub would suit her well. Does anyone have any recommendations or good experiences with social groups in Geelong?
