I'm much in the same position meself, me Mrs likes 60's, 70's, 80's, chart and non-chart, a bit of northern, motown etc so this type of thing would be right up her street. She'd love a night where they would play for example It's A Love Thing by The Whispers and next track play Do I Love You by Frank Wilson. I know everyone will go "Urgh" but that would appeal to her
