21st birthday

Do I look embarrassed? Well I was. This was the lunchtime show on my 21st birthday. 1968. The guy in front is David, the head waiter.
I just noticed that Jimmy has a different guitar. I have no idea what kind it is. Does anyone recognise the make? Some of the songs that we performed then would be Rose Marie, Ghost riders, Greenback Dollar and a host of join in, comedy type songs. It's strange how some things we forget, while other things stay so vivid in our memories.
