From 26 March to 3 April 1986, the band toured Germany, the Netherlands and Denmark on their "Easter Metal Blast" and in June, played two dates in Bologna and Milan in Italy. The court case with Bronze was finally settled in the band's favour. The band's management instigated their own label, GWR. Recording took place in Master Rock Studios, London and the single "Deaf Forever" was released on 5 July as a taster for the Orgasmatron album, which was released on 9 August. On the same day as the release of the album, Lemmy and Wurzel were interviewed by Andy Kershaw on the BBC Radio 1 Saturday Live show and "Orgasmatron" and "Deaf Forever" were played. The single reached No. 67 and the album reached No. 21 in the UK charts.  On 16 August, the band played at the Monsters of Rock at Castle Donington and was recorded by BBC Radio 1 for a future Friday Rock Show broadcast. The performance closed with a flyover by a couple of Second World War German aircraft. Also that day Lemmy was filmed giving his views on spoof metal act "Bad News" for inclusion in a Peter Richardson Comic Strip film entitled "More Bad News" since the band featuring Rik Mayall, Peter Richardson, Nigel Planer and Adrian Edmondson were also performing at Donington. In September the band conducted their "Orgasmatron" tour in Great Britain, supported by fledgling act Zodiac Mindwarp and the Love Reaction. In October they toured America and in December were in Germany.  In 1987, during the filming of Eat the Rich - in which Lemmy was taking a starring role alongside well-known comedy actors such as Robbie Coltrane, Kathy Burke, the regulars from The Comic Strip ensemble, and various other musician cameo appearances - Gill left the band and Taylor returned to appear in the band's cameo as "In House Club Band" alongside Wurzel and Campbell. The band wrote "Eat the Rich" especially for the film, its soundtrack featured tracks from Orgasmatron and Wurzel's solo single "Bess". The band's second album for GWR was Rock 'n' Roll, released on 5 September, after a tight work schedule in the studio. While having some popular tracks and using "Eat the Rich" as its second track, the band commented that the album was virtually "nailed together".  On 2 July 1988 Motorhead were one of the performers at the Giants of Rock Festival in Hameenlinna, Finland. The tracks were released as No Sleep at All on 15 October. A single from the album was planned with the band wanting "Traitor" as the A-side, but "Ace of Spades" was chosen instead. When the band noticed the change, they refused to allow the single to be distributed to the shops, and it was withdrawn and became available only on the "No Sleep at All" tour and through the Motorheadbangers fan club. While they continued to play live shows during 1989 and 1990, Motorhead once again felt unhappy with their career, and a court case with GWR followed, which was not resolved until mid-1990.
