20d Virtual preparation relating to calves (7) V - t - l - r. It ends in r if the answer to 27a Acceptability on a mass cultural level (6-4) is street cred. Maybe a compilation error ?
22a Prompt (7). Letters are either - i - l - n - or - r - l - n - because the answer to clue 20d delve (3) must be either dig or pry ? Thanks in advance
