Ordinary Bitter & Low Alcohol Beer

This weekend my Dad and I talked a little about Ordinary/Standard bitters, and other low gravity - low alcohol beers. I really enjoy an English Bitter beer, and particularly like the lower alcohol content for those weekday nights. Some evenings you really want to enjoy that second or third pint, but can't afford the 'slightly off' morning that sometimes follows three pints of Double IPA (does this make me officially old?). I usually have a Bitter or English Mild on tap for this very purpose, however it's somehow fallen out of my recent lineup. It's summertime and I'm primed for Pilsners, Wits, and Cream Ales....just maybe I'll sneak a bitter in there somewhere.
