Erapalli Prasanna was making his comeback having been out of the team for five years, while both Venkatarghavan and Bedi played in the series against West Indies.
Over the years, the spin quartet played vital roles in several memorable victories for the Indian team, starting with an overseas series win against New Zealand in 1967–68.
Below are some major Test successes the quartet were a part of: Out of the four, only Venkataraghavan and Bedi played regular one-day cricket for India.
Bedi was an orthodox left arm-spinner, while Chandrasekhar an attacking leg-break bowler whereas Prasanna and Venkataraghavan were both off-spinners.
