American band Guns N' Roses, who will play their first show in Singapore at the Changi Exhibition Centre on Saturday (Feb 25), no longer do hard-partying, it seems.

Among their requests while on tour - a full gym backstage so they can work out before their performance, said show promoters LAMC at a press event on Thursday (Feb 23).

The band, their crew and entourage arrived in Singapore on Wednesday evening (Feb 22) in a private plane that sports their iconic logo.

The Straits Times understands that core members - singer Axl Rose, guitarist Slash and bassist Duff McKagan - are staying at the Marina Bay Sands. Rose, one of rock's most prominent frontmen, is believed to be putting up at the hotel's exclusive presidential suite, which according to its website, includes a baby grand piano.

According to LAMC, the concert is one of the biggest rock shows held in Singapore, with close to 50,000 tickets sold. The only other concert to take place at the outdoors venue was a gig by American metal icons Metallica, which drew 40,000 in a 2013 show also organised by LAMC.

All parking slots, except for handicapped parking, have been taken up and heavy traffic is expected at the venue on show day. There will be drop-off and pick-up points for taxis and other transport but concert-goers are advised to buy tickets for shuttle buses, which will ferry them from Singapore Expo to Changi Exhibition Centre.

After the concert, the buses will go to five drop-off points - Singapore Expo, Bedok MRT, Tampines MRT, City Hall and Bugis.

Concert tickets from $199 and shuttle passes at $15 are available from Sistic (www.sistic.com.sg or 6348-5555).
