Question: The famous chain of music-themed restaurants opening its first establishment in the British city having the George Inn was founded by who?

<P0-S0> the keg is a canadian - owned chain of steakhouse restaurants and bars located in canada and the united states. <P0-S1> the original ``the keg and cleaver ''restaurant was founded by george tidball, in 1971, at a location in north vancouver, british columbia. <P0-S2> by february 2018, the keg had expanded to 160 locations in canada and the united states, when canadian food industry giant cara operations (now known as recipe unlimited) purchased the chain for $200 million, from then owners david aisenstat (49%) and fairfax financial (51%). <P0-S3> aisenstat had been the sole owner from 1997 until 2014. <SEP> <P1-S0> in europe, it is the provision of accommodation, if anything, that now distinguishes inns from taverns, alehouses and pubs. <P1-S1> the latter tend to provide alcohol (and, in the uk, soft drinks and often food), but less commonly accommodation. <P1-S2> inns tend to be older and grander establishments: historically they provided not only food and lodging, but also stabling and fodder for the traveller's horse(s) and on some roads fresh horses for the mail coach. <P1-S3> famous london inns include the george, southwark and the tabard. <P1-S4> there is however no longer a formal distinction between an inn and other kinds of establishment. <P1-S5> many pubs use "inn" in their name, either because they are long established former coaching inns, or to summon up a particular kind of image, or in many cases simply as a pun on the word "in", as in "the welcome inn", the name of many pubs in scotland. <SEP> <P2-S0> London has numerous venues for rock and pop concerts, including the world's busiest arena the o2 arena and other large arenas such as Earls Court, Wembley Arena, as well as many mid-sized venues, such as Brixton Academy, the Hammersmith Apollo and the Shepherd's Bush Empire. <P2-S1> Several music festivals, including the Wireless Festival, South West Four, Lovebox, and Hyde Park's British Summer Time are all held in London. <P2-S2> The city is home to the first and original Hard Rock Cafe and the Abbey Road Studios where The Beatles recorded many of their hits. <P2-S3> In the 1960s, 1970s and 1980s, musicians and groups like Elton John, Pink Floyd, David Bowie, Queen, The Kinks, The Rolling Stones, The Who, Eric Clapton, Led Zeppelin, The Small Faces, Iron Maiden, Fleetwood Mac, Elvis Costello, Cat Stevens, The Police, The Cure, Madness, The Jam, Dusty Springfield, Phil Collins, Rod Stewart and Sade, derived their sound from the streets and rhythms vibrating through London. <SEP> <P3-S0> On June 14, 1971 he and Peter Morton started the first Hard Rock Café (HRC) restaurant in London's fashionable Mayfair district. <P3-S1> The restaurant combined rock music, memorabilia related to rock 'n' roll and American cuisine. <SEP> <P4-S0> CAMRA maintains a "National Inventory" of historical notability and of architecturally and decoratively notable pubs. <P4-S1> The National Trust owns thirty-six public houses of historic interest including the George Inn, Southwark, London and The Crown Liquor Saloon, Belfast, Northern Ireland.
