Episode 45 sees us still in January 1923, but on the move...

First BBC Director of Programmes Arthur Burrows visits 5IT Birmingham and 2ZY Manchester to see the 2nd and 3rd BBC stations in action - so here's a podcast snapshot of what broadcasting was like in their makeshift studios in British broadcasting's earliest days.

Our guest is Jude Montague, whose grandfather Sydney Wright was an early on-air musician in the 2ZY Wireless Trio. And you'll hear the voices of those who were there: Kenneth Wright, Victor Smythe, Percy Edgar, A.E. Thompson...

Hear of singers toppling off platforms made of books, as they step back for the big final note. Hear of Manchester beating London to be first station to broadcast Big Ben. And hear of the Grenadier Guards Band, cramming 22 performers into a studio space fit for 3.

• Jude Montague's website - which will include details of her graphic novel about her grandfather Sydney Wright - is at www.judecowanmontague.com

Next time: another grandchild of an early radio wonder: Justin Webb on his grandfather Leonard Crocombe, first editor of the Radio Times.

Thanks for listening!
