Dylan - both of those clues are non-thematic so have misprints in them.
Full acceleration - try playing around with some abbreviations. First word = definition.
Brag for one - again definition is the first word.
Like others, took me a while to work out what was going on but, as is so often the case, once the PDM occurs, it all falls into place.
Seriously impressive amount of thematic material & some tricky misprints too - thanks KevGar for a challenging, enjoyable and, ultimately, unambiguous work out for a Sunday morning!
