[r-t] Bobs only peal of Plain Bob Triples

[Robert Bennett]

In Bob Triples, St Simons etc., a bob where 7 runs in or out affects the
coursing order of 4 bells, putting it out of course. 

To make a touch with one single, there have to be an odd number of Ins +
Outs. 

 John Holt composed a peal of PBT with no singles with one Q set of the
7th In, Out and make the bob, joining the other courses on. It is still
tricky, because the total number of courses is even, but it is possible
because the leads are reversible. 

He adapted the peal for Bob Minor, producing a 720 with no singles, where
the treble dodges once 56 up, once 56 down and makes 4th once.

 Yes, they are pretty well known.

 The RW Diary touch of 154 with one single is another curiosity.
