"The Strange Re-birth of Liberal England" was by David Walter. Stuart Mole wrote a book with David Steel. Is Tony Greaves still a secondhand book dealer? If so he's probably got copies of both of them. I don't.
There was also a book by Ian Bradley called "The strange re-birth of Liberal Britain"which I still have on my shelves. Ian Bradley was / is a Church of Scotland minister who has written a whole range of books, on Victorian history, Celtic spirituality, hymns, one of the early "as it was happening" histories of the SDP. He wrote a good book on evangelicalism in Victorian Britain, which I think was based on his Ph.D. thesis
That book was called Breaking the Mould? (highly original!). As it was written in the same year that the SDP was founded, it's quite useful for finding out about the roles played by several minor but influential characters who have since been mostly left out of the narrative. The more famous book on the party by Crewe and King, although much longer, focuses retrospectively on the Gang of Four and the 20-odd defecting MPs rather than these people. Bradley was a political correspondent for the Times in the early 1980s, so the book was based on many of the articles he wrote then. I didn't know anything about his subsequent career though, which sounds fascinating.
Arthur Horner (1894-1968) President of the South Wales Miners Federation General Secretary of the National Union of Mineworkers
Communist candidate in Rhondda East, 1929, 1931 and 1933 (by-election) in which he got 15%, 32% and 34% of the votes (respectively). He was replaced as CPGB candidate by Harry Pollitt (the General Secretary of the CPGB) in the 1935 and 1945 general elections. Pollitt got 45% of the votes in 1945 and was defeated by a margin of only 972 votes; if Horner had been kept as candidate, he would have got more support from the local miners and would probably have won the seat - and the CPGB would have got 3 MPs instead of 2.
