Going into the pits early in British GP, Walker took the Lotus 72 back into the race and as the leaders Ickx, Fittipaldi and Stewart came up to lap him on lap 23 Walker suddenly found form, Fittipald taking a couple of laps to get by, and when he did, Walker clung on, his 72, as tail out as Peterson would drive the car the following year, and extraordinarily under pressure and possibly hitting oil from Ickx Ferrari, Fittipaldi, slipped and Walker passed, and the extraordinary cameo continued, until an increasingly annoyed and fist waving Fittipaldi, was allowed thru by Walker, whose race effectively ended the following lap when he came up to lap backmarker Niki Lauda, the Austrian in an uncompetitive March 722, the Austrian, restoring order by not giving way to the equally lowly rated Australian.
