Pretty certain stalls standing for Hammersmith is at the back when it is not an all standing concert. Frequently the stalls standing tickets only go on sale when the venue is almost sold out. Think the ticket prices are another clue.

Wondering now if TBA is not now to be a second night at Hammersmith. Agencies have plenty of Hammersmith tickets left so initial ticket sales cannot have been outstanding.
Glasgow or Gateshead would be great !!
