Forty years ago this weekend, Mr Henry Gordon Jago met Professor George Litefoot... and we're celebrating this Doctor Who moment with a weekend of special offers...

Created by esteemed Doctor Who writer Robert Holmes, the double-act of Jago (Christopher Benjamin) & Litefoot (Trevor Baxter) may only have shared a couple of episodes of the classic Doctor Who - The Talons of Weng-Chiang, but it was a partnership that fired imaginations - and which Big Finish were eventually able to renew when the gentlemen returned for Doctor Who - The Companion Chronicles: The Mahogany Murderers in 2009 (a title which this weekend is available for £2.99 on Download and £5 on CD).

Since then the Jago & Litefoot range has seen the release of twelve boxed sets, and a number of other assorted Doctor Who adventures for the Infernal Investigators, and all this weekend it's our delight to announce special offer prices on them:

The first set - Jago & Litefoot Series 1 - is just £10 on Download and £15 on CD, while the following nine series are each £20 on Download and £22 on CD, with Series 11 and Series 12 priced at £25 and £30 respectively.

For this weekend, their meeting with the Sontaran Strax (Dan Starkey) from the new series of Doctor Who - Jago & Litefoot & Strax - The Haunting is £10 and £12 respectively, and two voyages with the Sixth Doctor (Colin Baker) are each £2.99 and £5.00. Their part in The Worlds of Doctor Who ensures a special offer price for this collectible set of £20 and £25, while their first encounter with the Fourth Doctor (Tom Baker) since the Talons of Weng-Chiang, Doctor Who - Justice of Jalxar is £2.99 and £5.00. You can also get our interview with Benjamin & Baxter for the same price.

Two Jago & Litefoot Anniversary Bundles have been set up with all our Jago & Litefoot releases gathered together, for £320 on Download and £360 on CD. These special offers all end at mid-day (UK time) on Monday 27th March.

The most recent adventure for the Infernal Investigators was January's Doctor Who - The Fourth Doctor Adventures: The Beast of Kravenos. Still available for pre-order are Jago & Litefoot's two-part encounter with the Tenth Doctor in Doctor Who - Short Trips: The Jago & Litefoot Revival, and next month's Jago & Litefoot - Series 13.

All of these CD purchases unlock a digital version in your Big Finish account, and you can be listening within minutes of buying to any of these alarming adventures and episodic escapes for the fearless friends!
