When this happens I revert back to one of my old favourites; blackcurrent cordial.
Back in 1978, when I was working all the hours I could for a PA company, I used to drink Lemonade and Black in stead of beer. I found drinking beer and lugging speaker cabinets up stairs at 1 o'clock in the morning didn't mix.
Most blackcurrent cordials are much of a muchness. However, Schwepps' blackcurrent cordial is very distinctive. I've been drinking some for the last couple of days. Each time I pour some out its aroma takes me back to Eric's in Liverpool.
