The Rolling Stones' legendary 1977 gigs at the 300-capacity Toronto club El Mocambo are being officially released as a live album for the first time on May 13.

Live At The El Mocambo features the Stones' full set from the March 5 show, plus three bonus tracks from the March 4 gig, newly mixed by Bob Clearmountain. Only four of the performances found their way onto the Love You Live album that followed in September 1977, which was dominated by tracks captured on the band's '75 and '76 tours – with the full set having never been heard before.

The gigs became reality after the El Mocambo was identified as the potential setting for a secret booking. A radio contest was organised, in which the prize was tickets to see Canadian rock heroes April Wine, as well as unknown band The Cockroaches – who, of course, turned out to be The Rolling Stones.

The setlist featured the likes of Muddy Waters' 'Mannish Boy' and Bo Diddley's 'Crackin' Up', as well as staples such as 'Let's Spend The Night Together' and 'Tumbling Dice' – plus Big Maceo's 'Worried Life Blues' and Willie Dixon's 'Little Red Rooster.'

There was also the live debut of 'Worried About You,' not heard in studio form until 1981's Tattoo You, and more highlights, from 'Honky Tonk Women' to 'Hot Stuff.'

Ahead of the album's official release, The Rolling Stones have shared 'It's Only Rock 'N' Roll (But I Like It)' and 'Rip This Joint':

Live At The El Mocambo is available to pre-order on deluxe 2CD, classic black 4LP & coloured neon 4LP here.
