Second in the series marking the 150th anniversary of the birth of Johannes Brahms.
Tonight Richard Baker introduces music for four hands on either one or two keyboards, played by the duo pianists Bracha Eden and Alexander Tamir with Sylvia Greenberg (soprano) Gillian Knight (contralto) John Graham-Hall (tenor) Paul Hudson (bass)
Besides selections from Brahms's popular Waltzes, Op 39 and Hungarian Dances, the programme includes extracts from the Liebeslieder Waltzes, the F minor Sonata, and the Third and Fourth Symphonies in rarely-heard two-piano arrangements by Brahms himself. Eden and Tamir also talk to Richard Baker about why Brahms wrote some of his most significant music for four hands.

The Formula One
World Championship
The San Marino Grand Prix
In front of an ecstatic Italian crowd at Imola last year, Ferraris were first and second. Didier Pironi won the 14 car race, only to see title hopes dashed after an appalling accident later in the season. Patrick Tambay or Rene Arnoux could win for Ferrari again this year, but Nelson Piquet , one of the absent drivers 12 months ago, leads the championship this year and is looking spectacular in a Brabham.
